Tadvic was approached to find a way that a bilateral finger amputee (i.e. no fingers on either hand) could cut cheese, tomato etc for a sandwich.
We built several prototypes.
Then we found a suitable commercial knife that could be held between both palms
The Stirex knife is primarily for arthritic clients.
A physical test is the only way to work out what does and what doesn’t work.
Tadvic is willing to build simple prototypes to explore possibilities – but is happy when a client finds an existing commercial solution.
