From the 2018 Blade Show comes this custom CKF/Jake Hoback Knives collaboration that kills! Like the samurai swords of lore, we have put many 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! åÊWe 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! This is what we know from Wiki about the "kwaiken" blade (and by the way, if you havenÛªt already figured it out, Kwaiken + Hoback = Kwaiback!): TheåÊkaikenåÊ"was once carried by men and women of theåÊsamuraiåÊclass inåÊJapan. It was useful for self-defense in indoor spaces where the long bladeåÊkatanaåÊand intermediate swordåÊwakizashiåÊwere inconvenient. Women carried them in theiråÊkimonoåÊeither in a pocket-like space (futokoro) or in the sleeve pouch (tamoto) for self-defense. When a samurai woman married, she was expected to carry a kaiken with her when she moved in with her husband."åÊ "Û_theåÊkaikenåÊis now calledåÊkwaikenåÊ(pocket knife). The modern term has no reference in historical records; also called aåÊfutokoro-gatana.Û
