Don't have a KZ, but have a BWM which I like very much. It is strapped onto my backpack now. HOWEVER... as soon as David finishes my sheath, I'll be replacing it with my B11. It is a better chopper, more comfortable and even lighter. No brainer. IMHO... price/performance... it is the best Busse deal out there. In fact, I just picked up another on the Exchange instead of spending the same price on a CABS.
