Summer is almost gone, at least in Europe. So there are even more reasons to grab our Magazine and share it with your friends. It's always good to have a positive springboard and take at least a virtual dive. All the divers among us know perfectly well just how relaxing water is for us when we finally descend. So before you get immersed in what we have prepared for you, read our opening article. Astonishing discoveries in the Lednica lake in Poland. Including a sword with a golden cross, an axe encrusted with silver, spears, arrow tips, crossbow bolts and many more. And above all – remains of a bridge from the times before the Polish state was formed. Incredible artifacts for both the European and global community. We are even more excited as Mateusz Popek, a member of our editorial team, was among the explorers. Congratulations! Since its beginning, Perfect Diver has been committed to protecting our Planet. On numerous occasions we were involved in cleaning various water bodies (in 2020, after signing an letter of intent with the Our Earth Foundation [Fundacja Nasza Ziemia], we facilitated one of the great finals of the campaign at the Strzeszyńskie lake in Poznań), we wrote about microplastic, opposed the idea of dolphinariums and objected to cutting sharks’ fins to cook soup. Sharks, those amazing sea creatures, almost at the very end of the food chain, are disappearing... The problem is very serious. An emotional text by Laura Kazimierska and a photographic account from Karolina Sztaba provide an explicit outlook of one the largest fish markets of this kind in the world. This issue is bustling with numerous interesting topics. Grzegorz Białas has made his photographic debut in our magazine, by picturing the magic Christine mine, described by Irena Kosowska. We're wrapping things up with some hints on how to get it on with cutting... See for yourselves and enjoy. Donations are always welcome, should you whish to support our editors.

archaeology

Ostrów Lednicki is the largest island on the Lednica lake, located in its widest part. There is a significantly smaller island Ledniczka located to the south-west from it and a tiny island called Ptasia Wyspa [Birds' Island] located to the north. On the first two islands the archeologists found traces of medieval gords and buildings. First settlers arrived at Ostrów by the end of the 9th century. A small gord (fortified wooden settlement) was built there at that time. We call it “tribal times”, as there is no evidence of state structures in this period. Perhaps the gord on the island was a residence of the local tribe's chief. However, information regarding this period is rather scarce, as later investments destroyed traces of life from that period. Around the year 950, huge investments were made on the island. A large fortified gord with a palas and chapel was built. A church was erected next to the palas. Workshops and merchant stalls appeared within the settlement beyond the gord walls. Life on the island was flourishing. Investments also included water infrastructure – two bridges leading onto the island were built. The engineering concept behind them was very bold. The first bridge headed towards Gniezno and was 180 meters long, whereas the second led towards Poznań and was as long as 430 meters. There was also a third bridge, which had been built slightly earlier, leading to the little Ledniczka island. One thousand years later the remains of those bridges will be in the spotlight of underwater archeologists.

the lance of St. Maurice, Bolesław also received the golden throne of Charles the Great, which unfortunately fell from the bridge into the water during transport. After Bolesław the Brave died, Mieszko II became the ruler. The beginnings of his reign were not easy and several years after he ascended the throne his country was overran by his neighbor, Bretislav I, duke of Bohemia. His army took over many gords and arrived at Ostrów Lednicki. A huge battle was fought on the bridges and the lake. Archeologists are finding its traces until today.

found there. The history of the islands on Lednica lake ends with that period. Later they were used as pastures and palas ruins were the fabric of legends. Ancient researchers were also interested in it. But the objects in the lake were forgotten. From time to time local fishermen mentioned snugging nets on some piles. In 1959, aÂ local clerk decided to check these stories and asked scuba divers to explore the lake. They found remains of bridges and numerous relicts, including the previously mentioned helmet. In 1982, scientists from ToruĹ&#x201E; started to explore the lake and still conduct their research there as the Underwater Archeology Center at Nicolaus Copernicus University in ToruĹ&#x201E;. It is not possible to mention all the relicts and present all research results, as it took several books and numerous scientific articles to hold them. In short, for almost 40 years archeologists have revealed the remaining elements of the bridges, studying their design and the materials used to build them. During their works they found numerous historical objects. These included everyday objects, farming tools and armor. Objects made of organic materials such as leather, wood or plant fibres are particularly valuable for archeologists. They were preserved thanks to the anaerobic sludge environment. This allowed us to learn what shoes looked like, how ropes were made, what spoons or bowls people used to eat at that time. Despite regular research, the lake surprises scientists every year. In the last few years many interesting historical objects were found there. One of Photo Andrzej Kowalczyk advertisement

Sardinia Northwest, Alghero

Text and photos Bartosz pszczółkowski

On the west coast of Sardinia, in the area of Alghero, there are limestone cliffs. They are rock formations majestically hidden in the blue waters of the Mediterranean Sea, full of mysterious caves with the famous Neptune's Grotto. There are more than 350 steps that lead to the cave, and inside it can fit the whole orchestra, which has already taken place before.

16 minutes, Patrizia reaches the nearest dive site called Grota di Enyo Falco (the Falcon Cave). An inconspicuous breach in the cliff, underwater, reveals itself as a majestic cavern with a sump leading to the dry part, with beautifully decorated walls and karst formations on the ceiling. Stalactites, stalagmites and columns create the image of a beautiful dripstone form, which is actually only available to divers. Here you can also admire the red coral (gold of the Mediterranean) already at a depth of 5 meters. It creates clusters of twigs up to the size of a human hand. Among such twigs, you can meet nudibranchs and various invertebrates. Alghero, along with the rest of the west coast of Sardinia, has been called the coral riviera for centuries, and the history of the exploitation of red coral dates back to ancient times. Underwater, the huge limestone blocks detached from the cliff and resting on the bottom just before entering the cave make a great impression. You can swim between them and, with a bit of luck, meet a spiny lobster waving its long antennae. Tunas flow here as well, but if it comes to a meeting, it lasts several seconds :). They are beautiful, large and very fast fish. After twenty-minute navigation on Patrizia, we reach the Punta Giglio massif. At this point, we can dive in Grota del Stalatiti (the Stalactite Cave), where at the end of a large tunnel

The final stage of the trip is the Blanco Tunnel, a white tunnel leading divers to the initial parts of the cave. Outside, sun rays shine through the blue waters of Punta Giglio and on the way to the boat we can meet groupers and schools of barracudas searching the surface layers of water looking for food. Once on the boat, divers usually begin to experience, share their impressions and get excited about this magical place. For everyone, this diving leaves an unforgettable memory of cave adventures.

cover the ceiling of the tunnel. On the wall you can sometimes see a slipper lobster or a crawfish. This dive site is so large that you can make four dives here and each dive will be different. The cliff walls go down to 40 meters deep, and at 30 meters there is a great entrance to the Kidneys Cave that is called Trasversale Bassa. At a depth of 15 meters is the heart-shaped main and most popular “cuore” entrance to the cave, and on the way back you can take a shortcut across Trasversale Alta to the exit. In the final part of the cave we go through Archi di Nereo – these are huge rock arches through which the light shines into the dark corridors of the Nereo Cave. You definitely have to dive here :) Diving around Alghero is unusual. The entire area is under protection and constitutes a national park. Thanks to this, the multitude of fish is noticeable with each dive. The vertical walls of limestone cliffs, perforated like Swiss cheese, as a result of karst processes, have left behind a magical landscape that is accessible to divers of all skill levels. Experienced divers will certainly benefit the most from the charms of these undersea wonders, but also beginners will be able to enjoy diving in the cavern space of many caves. The experiences they live will be remembered for a long time. To be continued...

Tremiti Islands Text and photos wojciech zgoła

September is one of my favorite months to spend time in the Mediterranean. If you combine it with a hitherto unknown piece of Italy and the memory of the taste of their ice cream, hidden deep in the taste buds, it can turn out to be a wonderful adventure.

characterized by the fact that the visibility under water often fails, which I have repeatedly confirmed by snorkeling. Determined, I wrote to my friend from DAN – Cristian. He responded enthusiastically to take a look at the Tremiti Islands. There are 2 diving centers there, and the dives will not disappoint me. Thanks to him (thanks Cristian!) I found out about the existence of islands in the Adriatic – belonging to Italy. After all, it is known that the Adriatic islands are Croatia – on the other side of the water.

And here is such a surprise!

Now I was checking ferry connections. From where to get to the Island , how long does it take to get there, how often and for how much. A positive surprise again. During the season, ferries run from every major town on the Gargano coast. Holidays started to fall into place. The Diving Center wrote back. The offer was interesting. Joy in the heart unrestrained. What can I say, I like discovering the underwater secrets of new places. The plane had one of the longest delays in my flying career. Finally, however, it touched the ground at the airport in Bari,

from where I rented a car to the suburbs of Vieste, where I was stationed for a week. The Gargano peninsula with the Gargano National Park covers about 2,000 km2. The interior is upland, but the coast is sandy, gravel or cliff. It is in the vicinity of Vieste, a beautiful city that was built years ago on a small hill, with wide, sandy beaches. I snorkeled here. A dozen or so kilometers from here there is a diving center with which I had an appointment for 2 dives next day. They called (luckily) in the evening and said there was a storm at night and the visibility was terrible. There is no point in diving. The next day they called again that the sea still hadn't settled down and there was no point in diving. The next day they found that they were actually finishing the season and didn't have time for diving... Fortunately, there were also the Tremiti Islands. I bought a return ticket and went on the ferry the next morning. There

were few people, a bit swinging, but after about an hour and a half, we reached another pearl of the Mediterranean Sea. I took a dry foot on the mainland of the Tremiti Islands. This mini archipelago consists of 5 islands, 2 of which are inhabited. Only in the summer season, the islands are visited by 100,000 tourists. When looking at its surface with the naked eye, the crowd must be wild and inexhaustible In that time! That's why I like September, among other things ;) The route from the marina to the diving base took 5 minutes, because I was looking around. A bit uphill to the right and I was already in Tremiti Diving Center. I just chose them. Not everyone spoke English, but as it is in Italy, they spoke, smiled and were friendly. After completing the formalities with a group of 8 Italians, I found myself on the zodiac. We were supposed to dive between the islands of San Domino and San Nicola. A rollover and salty, blue water cooled the body tired from traveling. It was great because I was under the water. I immediately noticed that there is a lot of life here, and the shape of the water rocks is very varied. We met 4 species of nudibranchs, rockfish, moray eels and barracudas. There were, of course, the crabs and drobica characteristic of this sea. The second dive was in a smaller group. It turned out that the older men who are here on vacation often dive only once a day. We descended to a depth of over 25 meters. The water

temperature at the bottom was 20°C. At the surface of 27°C. We dived while admiring the landscape. At one point, I noticed two small rockfish sitting on a rock shelf with their mouths facing each other. I stopped and watched because this is the first time this picture happened to me. After a while it turned out that these two fish are fighting for territory. They pressed against each other, jumped back and rested. I don't know how long it lasted and how it ended. As a straggler from the end of the peloton, I was called to a group whose beginning I have not seen anymore. This is how only one in the group tries to take pictures. After a day of break and sunbathing, I went back to the base to dive around the Tremiti Islands. This time we were diving with the base owner, nice Antonio. He showed us narrowings, tunnels, caves and crevices. Very diverse landscapes, full of life. Here I saw a snail with a "house" the size of an adult's hand. The second dive took place in a place with a slight breeze. The currents herald larger fish. Mostly. We met a large grouper. It was a good meter in length. Herds of barracudas that initially kept their distance and then flashed very close to us. Thousands of chestnut chromis, sarpa salpa fish, oblad and others swam around. Foaming waves could be seen above us. Big blue accompanied us at the safety stop, and on the surface it turned out that from this side of the island the waves reach 1.5 heights. After a while we breathed a breath in the port. It stopped swinging and my thoughts wandered to the restaurant... I was delighted to hand over the newest issue of Perfect Diver Magazine to the owners and put our sticker on it. When you had no idea for another trip, I sincerely recommend the Tremiti Islands. Very positive dive, with a good, friendly atmosphere. I liked it so much that I would like to go there for the whole week. Out of season, of course. It could be in September. I like September on the Mediterranean Sea 

safari gives you the opportunity to penetrate the diving sites around the islands – both from the coast and the open sea. We started the expedition in the small port of Sukošan, located about 10 km from Zadar, in North Dalmatia, on Vranjak 1. It is a steel, 27 meter ship, built by divers... for divers. The boat has 10 air-conditioned double cabins with bathrooms, a living room with dining area, a diving deck and a sundeck. There is cleanliness and order everywhere. Delicious meals! The organisation of dives is impeccable: short and specific check-ins, smooth filling of cylinders, peace of mind and relaxation. The opposite of a diving safari in Egypt – we do not get up at 5.30 and do not dive at 06:00! Here the time flows slower and calmer. Due to quite deep dives, there are 2 descents underwater during the day and one night dive during the whole week. Tomislav – the owner, a diving instructor and our diving guide, from the very first moment introduces us to the climate of safari and tells about the specifics of diving in the Adriatic. Here, each of us is an independent diver. We do not dive blindly following our guide, we do not descend to the depth to which our group descends, but only to the depth to which our powers and well-being allow us. Kind of obvious, and yet I have the impression that diving in different places in the world strictly under the care of diving guides, we forget to "think" underwater on our own.

My impressions after diving? Priceless! The wreck of Teti is also worth mentioning. It is a wreck of a steamboat which, when hitting the islet of Mali Barjak, landed at a depth of 35 m in 1930. The most remembered feature of this wreck is the spare steering wheel, luxuriantly covered with yellow and purple sponges. The ship was carrying paving stones, which were scattered on the sandy bottom around the wreckage. Teti lies at a depth of 11 to 36 m. It is definitely more damaged than the aforementioned Vassilios T. The area around the wreck is covered with grass, moray eels and slipper lobsters, and we are surrounded by a charming school of rainbow wrasses, parrot fish and cuckoo wrasses. "Abandon all hope you who enter here" – this was the inscription on the gates to hell in Dante's Divine Comedy. The heroes of one of the songs are the lovers Francesca da Rimini and Paolo Malatesta.

of extensive geological activity as the African tectonic plate slipped beneath the Eurasian tectonic plate to conquer part of the Earth's surface. The surface of the islands is dominated by karst formations composed of limestone and dolomite, caves, hollows and valleys that are partially underwater. Diving here is pure pleasure! The water seems more crystalline and the marine life is richer! The vertical walls fall to aÂ depth of several dozen meters, and in the rock crevices we had the opportunity to see crawfish, scorpion fish, octopuses and moray eels, which were so numerous here!

it is hard to get bored underwater. The stunning walls are covered with giant fans of purple and red gorgonians! We will also see the underwater wealth of many varieties of snails, echinoderms and anemones with a huge variety of colours, shapes and sizes. In addition, we have got there crystal clear water as befits a national park! At shallower depths we watched sea cucumbers, octopuses, anemones, swinging crinoids, starfish or bristle worms. What is more, it was during dives in the Kornati National Park that I saw the famous Peter fish! It is a very distinctive fish, strongly flattened with a distinct black eye in the centre of the lateral surface of the body. Legend has it that St. Peter while still being an apostle of Jesus caught this fish on Christ's command to get a gold coin out of its mouth. Before joining Christ, however, he was a blacksmith, so his hands were always dirty and black because he was constantly working with metal. When he caught the fish, two black spots remained on it from his fingerprints. In this way, the fish was called Peter, or the fish of St. Peter. The Adriatic Sea can really surprise you! Days flow like waves. On the penultimate evening we got to a small settlement with a stone pier called Levrnaka. Besides two fantastic dives during the day, we also did a night dive.

– which can change its colour by adjusting to the colour of the surroundings... It is here that I was able to see the conger for the first time in my life! It is a predatory sea eel resembling a moray eel with a different mouth. Its head resembles a dog's snout; it has large, blue-grey, glassy eyes, which we most often see first in the reef crevice where it hides. The goal was achieved, we could go home  The undeniable advantage of a diving safari in Croatia is the opportunity to see different diving regions during the week, as well as evening stays in the marinas. Every afternoon or evening, we moored in a port chosen by the captain, including Vodice, Rogoznica, Vis, Komiža or Primosten, plunging into narrow stone alleys leading between old town buildings. You can feel the magic of summer in the air. We spend every evening walking, admiring local monuments or tasting Croatian delicacies in atmospheric restaurants. This is how we can live! The sunset from the top of Lavrnaki is breath-taking. The landscape reminds me of the National Park Komodo (Indonesia). We are slowly saying goodbye to the crystal waters of the Adriatic Sea. Once again, I found out that diving allows you to release everything that is best in you, and a diving safari shows that Croatia, so known to us all, can be rediscovered. You just have to change your perspective sometimes. "We do not need better technology, better phones anymore. We need more feelings and sunsets."

Life was bustling underwater! Crabs, crawfish, sea urchins, shrimps, cuttlefish

If for any reason we feel a growing nervousness – let's act immediately. Immediate action is necessary to ensure that stress or fear does not turn into panic, because in panic one does not act rationally.

We signal the partner that we need help. We can lie on the water on our back and relax in our own ways. Or we can use the very simple breathing procedure. We focus on breathing as slowly as possible in order to breathe out properly. We focus on counting the seconds of the breath. Breathe in counting to four, breathe out counting to five. We repeat the procedure a few or several times. It often helps to close your eyes and hold your partner's hand. It is especially important to breathe out thoroughly to get rid of the carbon dioxide in the lungs. It is worth training the entire procedure on the surface (to develop a habit) and testing it under various stress conditions. It really works  Finally, familiarize yourself with the basic diving signs so that you can communicate with your surface assistant without using your voice. And you must know the signal of calling for help on the water, which is a wide wave of arms and hitting open palms on the water surface. But the most important thing is to plan everything to avoid any dangers before going snorkeling. And have a great time with our snorkeling partner while enjoying the stunning beauty of the water.

However, they would not do without their parents who look after them until they learn to hunt efficiently and become fully independent. Before this happens, the young take refuge under their parents' wings, literally! The parents of young grebes carry them on their backs, and it happens that they even dive with them. The coloration of young birds is different from mature birds. In addition to the characteristic stripes, young grebes have featherless spots near the head. Bird behavior researchers found that the young use these spots to send signals to their parents. When the spots swell or change color, it is a signal that adolescents want a snack, play or fulfill some other life need. After about 10 weeks, young grebes resemble adults, although they may retain some traces of juvenile coloration. At the end of the season, as it gets colder and colder, the grebes begin to remember what it was like to flap their wings, because most of them will fly south and west where they will spend the cooler part of the year. Seeing a grebe in flight is a real treat, because most often it is possible to see a flying grebe just during migration. During the season they fly reluctantly. They choose diving! Fish are often featured on the grebes' menu

which results in greater reproductive success. The male of the straightnosed pipefish, however, does not form a brood pouch, but carries spawn glued to the underside of its body. The males of both of these species take care of their eggs until they hatch, which makes them, next to the shorthorn sculpin and lumpfish (described in previous issues), the best Baltic fathers. They are peaceful fish that usually do not run away even from very curious divers. It often happens that they themselves get tangled up in a diver's gloves. They mainly eat small zooplancton. Due to climate change, there are fewer and fewer pipefish in the Baltic Sea. It is related to the disappearance of underwater meadows and the extinction of seagrass (Zostera marina). Therefore, both of these species in Poland were under strict species protection for a long time. However, the condition of their population began to improve and therefore they have been under partial protection since 2014. In addition to the coastal waters of the Baltic Sea, they can be found along the coasts of Europe, the Mediterranean, the Black Sea, the Azov Sea, and also in the Atlantic Ocean. It is best to look for them at shallow depths, above

AÂ fish worth more than gold

Text laura kazimierska Photos karolina sztaba

Due to the fact that I spend most of my time underwater in the company of these beautiful creatures and I am fascinated by the underwater world of the ocean, I delayed my visit to the infamous market as long as I could. After 7 years of living on Gili Air and Trawangan islands, it was finally time to face the fear and get to know the dark side of paradisal Indonesia, which is known to most, but few want to remember it on their dream vacation. An additional motivation was the cooperation with the organization The Dorsal Effect, which aims to provide an alternative lifestyle for fishermen from the Tanjung area. We woke up before sunrise, accompanied by the morning prayer coming from the mosque. In half-asleep, together with Karol (a photographer known under the pseudonym Karolatakesphotos), we got ourselves into a motorboat to get to Lombok. The driver was already waiting for us there. The goal was to reach the market at the same time as the fishermen returning from their catch. Three hours by car amidst the picturesque landscape of Lombok full of green coconut trees (seen from behind the car window) and we were there. Many warned us about the musty smell of fish decaying in the hot sun. However, in reality the stench exceeded all my expectations. The odour of the market could be felt long before entering the parking lot, so our driver did not even have to say that we were almost there. I covered my face with a handkerchief to prevent the irritating scent from going straight to my

However, this is in no way supported by scientific knowledge, but rather by beliefs. Given the enormous mercury content of shark meat, it is hard to believe that it has any therapeutic value. Quite the contrary. Even so, it is still a symbol of wealth and prestige, often served at banquets and weddings to show class superiority. Since the 1980s, the development of the economy in China and its economic importance have stimulated the appetite of the new rich for the cult delicacy. The result is an enormous demand for the product, leading to the death of up to 100 million sharks per year. The question is whether it is worth it? Answer for yourself.

Shark fin infusion was first mentioned in China in the 10th century, during the Song Dynasty. It has become a symbol of wealth, status, hospitality and all prosperity. Available only to the chosen and richest members of the community, it quickly became a symbol of class superiority. Between the fourteenth and seventeenth centuries, with the increase in wealth, it gained in popularity and at the same time became much more accessible. Since the 17th century, the demand for this unique delicacy has been growing steadily with the rapid population growth. With China's 60 million inhabitants during the Sang Dynasty compared to 1.4 billion today, shark fishing to get this regional specialty has become a serious environmental threat. The broth-like soup is made with chicken or pork, and the valuable fin is only for decoration. Many believe that the in-

ever, we need to understand that the profit they get is only a tiny part of the value of the commodity that smart traders buy and sell. Currently, the value of a dead shark on Tanjung Luar ranges from $ 70 to $ 100. The profit is distributed among the fishing families who have no other job alternative. Sometimes the only thing fishermen get in return is one or two pieces of fish to provide them with food. Importers, on the other hand, estimate the value of the fins in the range of $ 400 per kilogram, not to mention that for whale shark fins or the Basking shark fins, the price can even reach $ 10,000 or $ 20,000 apiece. Simple fishermen don't realize that the same ALIVE shark would make more profit than a dead shark. Divers from all over the world come to Indonesia to admire these majestic specimens of nature and leave a huge amount of money for the state budget. However, this has no bearing on the lives of families like those of Tanjung Luar. The government is doing nothing to support them financially or to create a substitute kind of income. Hope is in us!!! Our captain and guide was a fisherman from Tanjung Luar. Today he is looking for blacktip reef sharks for us. His smile and excitement reach its zenith as he pulls our hand with all his strength to make us swim faster because he notices three young sharks on the reef nearby. It's hard to believe that someone so delighted to see them now, in the past stood in the same hangar with a machete in hand, ready to dismember and desecrate these wonderful and at the same time severely endangered species. The Dorsal Effect, with whom we went on an educational trip, Project Hiu, Divemastergilis and many other non-governmental organizations operate in Indonesia and take the initiative to transform fishing boats into eco-tourist boats, giving fishermen Indonesia has an extremely diverse underwater ecosystem

I am concerned about the current situation. I even have a dream, I go under the water and there is Nothing, no sharks,

no rays, NOTHING! As a result, we will soon be gone too, but maybe that would be better... I have been teaching diving in Indonesia for years and more and more often I notice environmental degradation for short term gain. Fishing boats with their huge nets appear on protected coral reefs and diving sites. More than once I had to cut fish, corals and myself from ropes and nets carelessly left at the bottom of the sea. I keep asking myself if anyone will notice that we've just caught the last shark in the world? Why is financial profit more important than the millions of species that had lived in harmony with nature before we appeared? People, intelligent, thinking, sensitive, emotional… supposedly. Is it worth visiting places like Tanjung? Absolutely! But visit them consciously. Sometimes you have to experience a shock and see with your own eyes a tragedy that you read about in newspapers or see in movies. It provokes reflection and action. Each of us can give something back by supporting organizations such as The Dorsal Effect or other local initiatives, and on your dream vacation, check what is really hidden behind a tempting tourist attraction. Taking people underwater and showing how wonderfully diverse and fascinating the world below is is my contribution to protecting our planet. The more people see that the ocean is not just a flat, blue surface, but a vibrant, hidden cosmos and an amazing ecosystem, the more people will appreciate it and therefore protect it.

Did you ever wonder why a diver needs a knife? You must have several ideas. 30 cm long, with a blade covered with sharp, saw-like teeth at one end and a steel “hammer” at the hilt’s end? The knife rests in a sturdy rubber sheath that may be attached in the calf area.

large piece of diving equipment. Once upon a time, a diving knife had several purposes: • during underwater searches it was used as a small “shovel” for testing the bottom; • the toothed side was used for cutting strings and cords of large nets; • the hilt with a steel head was useful for opening air tank reserve valves; • it was used as a small axe to prepare wood for a bonfire.

Sounds somewhat exotic? Several decades ago, divers often went for multi-day trips, diving camps and underwater searches. It was always an Adventure. Everybody knows that adventures are very often somewhat dangerous  For a good many years, brave men guarded their camps with various weapons, and being a diver meant that you were silently allowed to carry a really large knife  Grinning yet ? Then you are in for a surprise: today, almost every traveler and many people leading a sedentary lifestyle use EDC knives*.

Well, it's actually all about this “cutting”. To cut a single fishing line that we can clearly see, we need to catch it and stretch it, take out a cutting tool and find the fishing line with it. It often turns out that the device is more suited to cutting ropes, and it is not as good at cutting fishing lines... You will surely say “It isn’t so – I can cut any fishing line with my special forces titanium knife”.

to entanglement. Let’s think about the line cutting test for a moment and consider the matter carefully. You surely came to the following conclusions: 1. Cutting a single fishing line is difficult even in a perfectly controlled environment. 2. Cutting a single fishing line is much more difficult when it is placed behind your back. 3. Underwater, a diver usually gets a part of their equipment on their back caught on a single fishing line. 4. An attempt to cut through it on your own may lead to an accident with serious consequences.
