THE PROBLEM: To allow someone with limited or no use of their fingers ( i.e. arthritis, paralysis ) to use a heavy sharp cutting-chopping knife safely .
THE SOLUTION: The knife is mounted to a universal joint made from 1/4" plastic (lexan) as shown in the above diagram. The unit is attached to the cutting board with a 1/4" stainless steel carriage bolt. The knife can then be swiveled from side to side, raised and lowered, and sawed in a back and forth motion. In some applications various adaptations to the handle can interface with a support worn on the hand. Add a raised lip and no more run away veggies. A smooth plastic board makes for easy cleaning. Spikes can be added to hold the item to be cut in place.
