I am familiar with the cold steel bushman, but have never found out how you are supposed to attach a shaft to it. Just pushing it onto the end makes no sense unless you are supposed to epoxy it in place and that would defeat the versatility of a knife that could be used as a spear.

The knife I am thinking about looked stock with standard hilt, but the handle was hollow and according to the advertisements I remember, the internal threads were deep and staggered like a threading die so that you could screw the shaft on and screw it off, put the cap back on the handle and it was a regular fixed blade knife again.

This was a long time ago and I suppose people on the Knife forum might be able to remember who made it.
