Since its introduction in 2011, Michael Janich’s Yojimbo™ 2 design has earned a respected place in Spyderco’s product line and legions of devoted followers worldwide. The YoJumbo builds on that success, scaling the design up by over 20 percent and refining its ergonomics to accommodate a wider range of hand sizes. Its formidable four-inch (102mm) Wharncliffe blade is hollow ground for superior edge geometry and features a fully accessible Trademark Round Hole for swift, ambidextrous, one-handed opening. The handle’s open-backed construction and nested, skeletonized stainless steel liners keep weight to a minimum, while its coarse-textured G-10 scales promote a positive, non-slip grip. A high-strength Compression Lock and four-position pocket clip complete the package, making the YoJumbo a truly formidable cutting tool optimized for personal-defense carry.

Designed by personal-defense authority Michael Janich, the YoJumbo is a supersized expression of his time-tested Yojimbo 2. Ideal for users with large hands and those who prefer longer blades, this dramatic folder is now available in an all-black format. Its hollow-ground CPM S30V Wharncliffe blade is cloaked in a low-profile Diamond-Like Carbon (DLC) coating and complemented by a matching black-coated four-position clip and handle hardware. Even the nested stainless steel liners that provide the structure for its Compression Lock mechanism have a stealthy black coating, making this expression of the YoJumbo perfect for use in environments where light discipline is a concern.
