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.
