The EnZo is a fine knife......thick, strong, sharp, and I have no problem with the ricasso or any other part. Ideally, you can get a Kit knife and put it together yourself. In doing so, there isn;t any part of the knife you can;t shape or adjust to suit your hand.
Or.......just order the blades and scale them yourself:

The Enzos are great knives. Try one of them, at least.....
