Like the samurai swords of lore, we have put countless hours into perfecting the Kwaiback into a knife that is as flawless as we can possibly make it.  We pulled out all the stops with this knife!  We cut no corners, nor looked for any easier ways to do it. This knife was built with hard work, for hard work.  Fully-engineered internal lightening pockets, hardened stainless steel lock insert, HRD (Hoback Roller Detent), hardened stainless pivot, and stainless pivot bearings. These are just a few of the things you get with a Hoback Knife. The rest you'll just have to see for yourself!
