Trifin / screwdriver

My design “Trifin“ is a universal concept for the handles of screwdrivers and other tools.
The lower amount of power that is needed is because of the defined ribs with their defined edges and surfaces and the ergonomically formed body of the handle. The form of the body causes a high contact to the skin of the hand and the ribs are points of vantage for the fingers. Both features follow the natural way of grabbing.
As a result, it enables weaker people to work successful with a screw driver again and makes working for the pros become more comfortable.
