Oh, I might just faint from internal bleeding. I cannot wait to see it. Baby (my pride and joy) is a Kopis-type short spear and it's functionality has been unlimited here in the Midwest. I might have to commission you for one just to keep my best friend from trying to run out the door with mine. Haha. Have you ever tried something with an enlarged (32-36 inches) handle? I'm sure it isn't too difficult, but it took me a while to get the balance right.
Did a naginata years ago, although I haven't done anything with a significant shaft lately. Mostly it's because it's a pain in a butt to mount the blade on and tough to ship, since I haven't done shows in like a decade now.
