Introduction: 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

    Great idea and great instructable. I initially saw this as a kitchen chopper, but not see its value as tableware.

    Thank you.

    Can this be purchased anywhere already assembled???? The person needing it only has 1side of their body that is functionable. Thanks.

    That's an interesting knife design, you could get more force behind it for cutting through tougher things. :)
