Interesting, so do you just use the eye bolt for angle adjustment but free hand the plunge, not using a stop bolt?
I agree with Natlek about moving the grind line more parallel to where the handle ends, the totally squared off grind makes it look like a kit knife shape to me. One other tiny detail that's really bothering me about the prototype so far is the pin at the back of the knife - it should be centered on the axis of the handle to look proportional IMO. Great work so far!
Add these 2 together and you got a winnerA bit more curve to the top corner of the plunge would be good, but end it ahead of the ricasso area(like your first picture) to keep your finger protected from the edge IMHO
