I didn't try anything fancy for my first go at it, but I did flute it. (I think that's what I did anyway, correct me if I'm wrong.) There are no barbs or serrations because both are illegal to hunt with here, and I make all my stuff intending to use it in the field. Well here it is:
I may have to haft the next one deeper into the shaft of the arrow, but maybe not. We'll see after a good shooting session. I used a dremel tool for just about the whole thing, including a light polish at the end. I haven't put a real good edge on yet because I can't seem to find my file.
Anyway, your comments and suggestions are welcome as always. I'm always looking for ways to improve.
