The Relieve Knife from etac simplifies cutting tasks because the serrated knife provides a better working position than ordinary kitchen knives. It has good balance in the hand, and it takes no additional strength to keep the blade of the knife up. The power grip can be used with a straight wrist, which makes better use of hand and arm strength.
This is a terrific idea for someone with arthritis or reduced arm, wrist or hand strength, as it employs your power as efficiently as possible.
