One Handed Cutting Knife

The knife is designed for people who suffer from some kind of hand function problems (e.g amputees, cervical nerve injury, elderly, general weakness) and have difficulties cutting their food.

The shape of the blade is designed so it goes under the hand, this way exploiting the power from the entire arm when cutting.

This project was done during Industrial Design studies at HIT- Holon Institute of Technology, in collaboration with "Fixperts" organization.

Design: Nadav Meir & Eran Zarhi
