shaving razor
brief history the revolution in the ‘art’ of shaving started with a man named King Gillette. Gillette's idea was brilliant in its simplicity. his goal was to create a small, inexpensive metal blade that would be sharpened in a factory and then thrown away when it became dull. this was the first product in history which was meant to be disposable. his patented drawings are shown, dated 1904
Gillette's idea for manufacturing was to take thin, rolled steel, stamp it into small, rectangular shapes and then sharpen the edges. that seems simple enough today, but at the time it had never been done. the problems he faced were 2 pronged… hardening the steel so that it would hold a sharp edge. the thin steel in Gillette's blades had a tendency to warp because it would cool quickly and unevenly. actually sharpening the edge of such a thin, small piece of metal. it took six years before he and an engineer named William Nickerson worked out the process… the heating problem was solved by sandwiching the blades between thicker pieces of copper during the heating and cooling process. the sharpening was achieved through increasing levels of automation. eventually, automation dropped the cost of each blade down to a penny, while they sold for about a dime each. the rest, as they say, is history.
the safety razor
brief history for the next 60 years, shaving technology stayed about the same, but for the advent of the electric razor. in the 1970s, wet shaving advanced again with the creation of the twin-blade cartridge. the idea had been around for awhile, but the revolution that occurred in the 70s happened from a marketing standpoint. gillette put its full weight behind the twin-blade concept with a huge advertising blitz, and schick then went head-to-head with gillette. everyone was taught that two blades were better than one through billions of dollars spent on advertising. development on the triple-blade razor began in the 1970s, but there were apparent problems with three blades. they caused irritation. in 1998 the solution to this problem appeared. the mach 3 shaving system from gillette uses three blades, but the blades are very small and each one is canted at a slightly different angle in the cartridge. the addition of lubricating strips, a flow-through blade design and other innovations made this the pinnacle in shaving technology. schick rose to the challenge by introducing the quattro, a four-blade shaving system. gillette countered with the gillette fusion, with five blades. it would seem that this would mark the logical extreme in the evolution of multiblade designs. surely, if you can't get a close shave with 5 blades, the addition of a sixth blade is not going to help.

user study
the following interesting observations were made for females • all respondents remained anonymous • 60% of users do not remember the brand names • most think hair can be easily washed out of the razor. • 40% do not know the cost of the razor • since it’s used in ‘emergency situation’, most don’t bother about it’s cost effectiveness. • general satisfaction from product is high for males • 60% think hair getting stuck is a major problem. • 80% throw away blades when they become blunt • only 40% think razors are cost effective • 60% think moisturizing strip is useless. • general satisfaction from product is good
