Since it's a hunting knife, if you continue doing these might not be bad to try some rifle cartridges, or maybe even let guys send their own. i.e. I hunt with a 35 whelen (not really, there's no scope on it right now) or a 30-06, I can send you the case you use that. man that'd be slick. It's like the ultimate version of the cartridge knives where it has the little shield shaped like a cartridge on the side. I bet these would be a hit at Friends of NRA dinners.
