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 patented 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.
