HATCHET KRISTEN JUSSILA
RE-EVALUATING THE
HATCHET Six working models were designed and tested with one control model to find the most comfortable and efficient hatchet handle.
TEST PLAN Testing took place outside of Gulfstream Center for Design at Savannah College of Art and Design in Savannah, GA. The test subjects used each of the test models for 30 seconds starting with the control handle and moving through the other handles in sequential order. The test subjects were told to “use the hatchet on this log”, then they were timed as they chopped a log at 3 feet high. The test subject was then asked “which handle is the best?” Afterwards they were given a questionnaire to complete.

INDIVIDUAL CONTRIBUTIONS RESEARCH Research started with initial brainstorming and ideation involving collaboration with the entire research team to determine our data collecting plan.
DATA COLLECTION Data was collected through two different interviewing methods, one using open ended questions and the other using cards to determine a sense of security and safety. Observations were conducted throughout the downtown area of Savannah. Photos and notes were taken to record all information.
TESTING Students were selected to test 7 different handles including one control. After testing the handles the students were asked about the efficiency and comfort while using each handle.
