Spyderco's Persistence is a small, yet efficient knife. Careful positioning of the oversized Spyderco Round Hole, relative to the location of the pivot, pre-set the hand in just the right spot for fumble-free one-hand blade open/close. Fully sharpened edge from tip to tang generates the most cutting edge possible for the blade’s length. Blade length: 2.75". Overall length: 6.8". Weight: 3.3 oz.
