Description

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. This elite expression of it supercharges the design with Böhler-Uddeholm's K390 MICROCLEAN® blade steel. A state-of-the-art 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 features Bi-Directional Textured fiberglass-reinforced-nylon (FRN) handle that is molded in the distinctive blue color reserved for Spyderco's elite K390 family of knives.

    Product & Price

    Posted by Eric on 16th Jun 2025

    National Knives has become my "Go To" Knife vendor. The price on my Leaf Jumper with K390 blade was so good I couldn't leave it behind. Discontinued means I almost missed it. The knife is right sized, has superb blade steel and is very easy to snap open(which surprised me). It's a great competitor for pocket time. GET ONE while supplies last.

    Leafjumper K390

    Because my Lil Temp K390 needed a pal and also like a Native without a choice. FRN and grip shape works well. Thinner blade stock tuned up at about 17 dps (Seki..) and shape is similar to Endela, Delica. Quick ship per Natl Rob and the cursory hand towel always appreciated WOOF!

    I always loved spyderco delica, but this knife is so much better. K390 steel stays sharp a long time with K390 steel

    Cool knife, great steal, needed some work

    Posted by Ryan M on 2nd Mar 2025

    I have a bunch of spydercos, but i’ve never had a seki city knife and i really wanted to try out the k390 steel. The factory edge was terrible out of the box! Uneven apex and there was still a burr present. Lucky i have some diamond stones, so i just sharpened it right away. It was a great steal to sharpen and very easy. I’ve been using the knife at work for a week and it seems to be holding an edge very well. Great deal too! Would have gotten 5 stars if the factory edge was good.
