Ergonomic Grip for Hand Tool
The second project focused on redesigning a common hand tool to have a more ergonomic grip . Using structural foam, wood, adhesives, painting and finishing techniques, we were to remove or adapt the grips of real tools to improve their ergonomics.
The tool I focused on improving the grip for was the can opener. The way in which I aimed to improve the design of its grip was to add concavities for a user's left hand to a wooden handle.

Concept sketch of a more ergonomic handle for a can opener. The addition of finger grooves and a pocket for the user's palm guide them to grip the opener in a manner that is comfortable and conducive to operation.
After creating concept sketches and getting my idea approved, I created a wooden prototype using a handheld Dremel, hand files, and coats of polyurethane as a sealant. I then removed the handles from the can opener, replacing them with my wooden prototype.
