I got a bit overzealous while hollowing the handle and ended up much narrower around the edges than I really wanted. The steel is 3/16" thick O1. The narrowest spot is a bit over 1/8" wide. I'd prefer the handle to have a bit more "meat" around the edges but I think it will be ok. What do you think, strong enough?
The scales are going to be carbon fiber or G10 bolted together with three 8-32 screws, so that should add a bit more strength.
