what is wrong with putting your index finger on the back of a knife?
the "pro" method of holding a knife is via the "pinch grip" and i have seen
an alton brown show where knife skills were discussed and he said not to put the finger on the back of the blade but didn't go on to explain why not.
on several other threads sandra lee was poo-pooed as an amateur for putting her finger on the back of the blade, but watch emeril and especially "iron chef" and you will see that finger poised on the back of the blade A LOT!! especially with iron chef, both the iron chefs and the challengers will put their fingers on the back of the blade (just watch!! they do!!) and i will put iron chef sakai's bladework up against ANYONE. (he's really good!!)
so i repeat the question ...
