It's my idea. I have it copyrighted so don't even think about it!
Actually, I've been playing around with wood carving and burning for a while. I did a knapped head in a handle a while ago and it got my mind churning.
I do seem to remember a guy posting here or on LW that did a much more stylistic snake or maybe it was a dragon on his handle a while ago.
I have another really cool idea but I'm gonna save that for later.....
