YoJumbo™

Michael Janich’s Yojimbo™ 2 design was instrumental in defining the genre of the “tactical Wharncliffe.” His 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.  

The YoJumbo’s formidable four-inch (102mm) Wharncliffe blade is hollow ground from CPM® S30V® stainless steel for superior edge geometry and features a fully accessible Trademark Round Hole™ for swift, ambidextrous, one-handed opening. Its handle showcases easy-to-clean, open-backed construction and nested, skeletonized stainless steel liners. These features keep the knife’s weight to a minimum, while its coarse-textured G-10 scales promote a secure, non-slip grip. The liners also form the foundation of its high-strength Compression Lock® mechanism and anchor its four-position pocket clip, which is configurable for tip-up or tip-down carry on either side of the body. A truly formidable cutting tool optimized for personal-defense use, the YoJumbo is available with a satin-finished blade and brightly finished hardware and in an all-black configuration with a Diamond-Like Carbon (DLC) blade coating and black-coated liners, clip, and handle hardware.
