Tadvic was asked to produce a combination roller knife/fork for one handed use (eg stroke or trauma victim).
We found a product sold in the US by a television marketing company – but they are no longer available. We also found a US/Canada health supplier – with a discontinued product. We could place a special order with a Chinese manufacturer with a minimum order of 2000 units.
So instead we made our own from a pizza cutter and a fork.
They work well for sausages, pies, vegetables etc but struggle with a tough steak.
We built two models – one for left hand and the other for right hand use.
