I like my Cold Steel Bushman. It'd take some modding to be able to hold anyting inside the handle, but it is a very capable blade as is.
I was watching Bruce Parry lastr night and one of the Bushmen he went out with in Africa was using a CS Bushman knife. i thought it was a marketing gimmick and even though I had heard the knives are good, I had no idea they were being used by actual bushmen in Africa! I'm sure the Bushmen wouldn't use any old crap knife, it would have to stand up to a lot of work and the one in the programme looked to be in fair condition.
I've heard newer production Bushmen knives are a bit crap and the steel quality isn't as good, I'll keep an eye out for one of the older ones though.
