The Kwaiback MK4 ultra high end production mid-tech by Jake Hoback offers all of the exact same features as his custom shop work. He didnt "skimp" on this knife nor use inferior materials or hardware. This knife will rival his custom work for fit, finish, materials and quality. This Kwaiback has a stonewashed tanto style blade & carbon fiber, titanium frame lock handle with the Hoback Roller Detent system on the lockbar and a CBP caged bearing pivot for superior blade action. Flipper opener and reversible tip-up carry pocket clip. Comes in a Hoback custom wood box..
