Inspired by Sal Glesser's original RockJumper design, the LeafJumper is a medium-sized, rear-locking folding knife with a large, ergonomic handle and a versatile leaf-shaped blade. This elite expression enhances the design with K390 MICROCLEAN blade steel from Böhler-Uddeholm. A cutting-edge tool steel created to withstand the rigors of industrial cutting, blanking and punching operations, K390 offers exceptional strength and edge retention when used in knife blades. The K390 LeafJumper is available in both PlainEdge and fully serrated SpyderEdge configurations, and its two-way textured fiberglass-reinforced nylon (FRN) handle is fashioned in the signature blue color reserved for Spyderco's elite K390 family of knives.
