Great work stick, really nice! Like all three.
That hammered "pinkie guard" really gives the impression of a full integral or peened on hilt. Very ingenious and creative.
Question. Did you do something to the antler to blacken it? Looks really black on my computer. Very cool.
Oh, and you might try clamping the blade between a couple narrow plates of aluminum while your forming the hilt if you keep having that warpage thing happen. It should pull the heat away and help hold it straight. Plus it won't scuff the blade.
Great work man. Keep um coming.
