Penknife with a 2 edge blade
Penknife with a 2 edge blade
Background
A concept design submitted for the 2007 Muji Design Competition.
Problem Statement
It takes a lot of effort to cut a thick material with a traditional cutter or penknife.
A penknife with a 2 edge blade is designed such that it can increase cutting depth by 2 times in a single stroke compared to traditional cutters. Thus, less strokes and less effort are needed to cut thicker materials.
