The Tenable Knives Fenrir is a fidget-friendly button lock knife designed by Greg Schob. It has a buttery smooth ball bearing pivot with an accessible button lock and a thumb stud opener. In addition to looking awesome, the blade has a built-in thumb ramp with jimping and a finger choil for additional grip options. The blade steel is super-tough Sandvik 14C28N, and the handle has skeletonized steel liners for lightweight strength. Fenrir is the name of a giant wolf in Norse mythology destined to consume Oden, and we can say for certain this pocket knife lives up to its name, even if you won't be using it to battle any gods.
