I've found I can be precise enough cutting with my non dominant hand!

but to be fair I suppose I'm also a bassist and keyboardist so I'm extremely accustomed to doing intricate things with both hands??

I have zero issues using a knife?

I agree in most other situations. It just feels unnecessary for cutting food right before eating. The fork in your right hand stabilizes the food being cut. The plate is usually very stable on a table. Of the countless times I have cut myself with a knife I was using for various tasks. Not once has been while cutting food on my plate while eating it.

I am convinced the safety argument is merely an attempt to justify something that is simply a table manners thing decided arbitrarily by some bored noble. The other excuse I have heard for it is that constantly having to put the knife down, and switch fork hands, slows down how fast people eat.
