Spyderco RockJumper Folding Knife, VG10 Blade, FRN Handles, Lockback

At first glance, the Spyderco RockJumper appears to be nothing more than a lightweight Wharncliffe-bladed folder sized to split the difference between Spyderco’s best-selling Delica 4 and Endura 4. If you dig a little deeper, however, you’ll realize that the minor nuances of its design reflect a much deeper logic and extreme attention to detail—the kind that only comes from the mind of its designer, Spyderco founder Sal Glesser.

The basic features of the RockJumper are consistent with many of Spyderco’s Japanese-made lightweight folders: a full-flat-ground VG10 stainless steel blade, a fully accessible Trademark Round Hole, a choice of PlainEdge or SpyderEdge configuration, skeletonized stainless steel liners, a sturdy lockback mechanism, an injection-molded fiberglass-reinforced-nylon (FRN) handle, a high-traction Bi-Directional Texture pattern, and a four-position pocket clip. As “standard” as all of that may sound, the real magic of this design is in the way all those proven features are expressed.
