I'm interesting in making a boning/fillet hybrid. It'll be an interesting project, and also very, very tricky I think. I don't really know what makes a good one though.
I noticed that nearly all of the ones I've seen have a guard and closed heel, but I want to have at least an open heel. A guard would be very difficult for me with my limited experience as well, but maybe it's doable.
Heck, I don't even know how one is properly used, particularly the grip; is it just a hammer grip most of the time?
Thanks for your expertise!
