Product Description
The Spyderco YoJumbo C253GPBBK is a supersized expression of tactical excellence, designed by personal-defense authority Michael Janich. Built to accommodate larger hand sizes and those who prefer a more substantial blade, this "Blackout" model is cloaked in a low-profile, non-reflective Black DLC (Diamond-Like Carbon) coating. The 3.98-inch CPM S30V stainless steel blade features a hollow-ground Wharncliffe profile, creating a perfectly straight cutting edge that delivers devastating power all the way to the acute point.
The handle is constructed with nested, skeletonized stainless steel liners that are also black-coated to maintain total light discipline. Coarse-textured Black G-10 scales provide a high-friction, non-slip grip, while the patented Compression Lock® ensures a vault-like lockup and safe, one-handed operation. Proudly made in the USA, the YoJumbo Blackout is a professional-grade defensive tool optimized for discreet carry and high-performance utility.
