Designed by personal-defense authority Michael Janich, the Spyderco 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.
