I am thinking of buying a BK9, and was wondering if anyone has done any modifications to the handle? I want to make it more "fighter friendly", by making a handle that doesn't slide (stickier), and has a bigger guard, so your hand doesn't slide onto the blade when stabbing. I would also like to make a sharp false edge to make easier penetration. Does anyone have any ideas/done this before? any help will be greatly appreciated! Thank you.
