Spyderco YoJumbo, Compression Lock, CPM SPY27 Wharncliffe Blade, Cobalt Blue G-10 Designed by personal-defense authority Michael Janich, the YoJumbo takes his legendary Yojimbo 2 and scales it up over 20% into a bigger, more capable cutting tool, built for serious everyday carry, demanding cutting tasks, and anyone with larger hands who wants more knife to work with without losing the control that made the original famous. The 3.98" Wharncliffe blade is deeply hollow ground from CPM SPY27, Spyderco's proprietary cobalt-enriched stainless steel that delivers a rare balance of toughness, corrosion resistance, and edge retention, a genuine step up in blade performance. The Wharncliffe geometry is purpose-built for controlled, precise slicing, whether you're breaking down cardboard or handling detail work. The handle is finished in striking cobalt blue peel-ply textured G-10 over skeletonized stainless steel liners, keeping the knife strong without unnecessary bulk. At the core is Spyderco's proven Compression Lock. One of the strongest, safest lockup systems available, easy to disengage with a natural pinch of the thumb while keeping fingers clear of the edge. The Trademark Round Hole gives you fast, ambidextrous one-handed deployment every time. A four-position pocket clip rounds it out, letting you carry tip-up or tip-down on either side, so the YoJumbo fits your carry style instead of the other way around.
