Inspired by Sal Glesser’s original RockJumper™ design, the LeafJumper™ is a mid-sized, back lock folding knife with a wide, ergonomic handle and a versatile leaf-shaped blade. Its lightweight fiberglass-reinforced-nylon (FRN) handle is molded in the distinctive blue color reserved for Spyderco’s elite K390 family of knives.
MODEL NUMBER: C275CFPBK. Designed by Eric Glesser, the ButtonUp™ is Spyderco’s first-ever manual-opening button-lock folder. The blade is housed in a lightweight, easy-to-clean, open-backed handle constructed with smooth carbon fiber/G-10 laminate scales reinforced with nested stainless steel microliners around the pivot and lock.
