The Carbon Fiber Kwaiback is the most improved and refined knife in our current lineup. The first thing you will notice is how little it weighs - only 4.6 oz.! Yet, it maintains the bomb-proof ruggedness that Hoback Knives has always been known for. The blade steel is superior CPM-Cruwear, paired with pivot thrust bearings, Hoback Roller Detent, Stainless lock insert with overtravel prevention, internal skeleton for light weight, standard screw sizes, and cold formed bearing races. This all adds up to a NPD (Never Put it Down), not just a EDC! We are a Hoback authorized dealer.
