I have something similar, but still pretty different in the works already. It has a little more curvature but follows pretty similar lines in the hand, at least on the spine side. It's kind of a blend of a Persian knife handle, a lamb skinner, and a Canadian belt knife. Here's just handle profile after gluing the wood pieces together for prototyping. I didn't show the blade because I'm unsure of the overall profile and orientation as there are a lot of curves to work out to make sure the edge ends up where I want it when the knife is held in a natural position. Edit: here's a version headed to the knifemaker for eval and cost estimates. I'm hoping to get this guy out in March or April. I think I'll tap into the resources of this group again as it worked out well for the last prototypes.
