Power meets precision—stealthily. The Spyderco YoJumbo (C253GPBBK) takes Michael Janich’s proven Yojimbo DNA and scales it up into a full-size 3.98-inch Wharncliffe built for confident control and deep slicing performance. Its long, straight edge amplifies pressure at the point of contact for explosive cutting efficiency, while the Black DLC-coated CPM S30V blade resists wear and corrosion and keeps reflections low for duty or discreet carry. A grippy, hand-filling Black G-10 handle with nested stainless liners and generous chamfers locks into your palm, and the Compression Lock® keeps fingers out of the blade path for strong, one-hand operation. With the Round Hole™ opener and a four-position clip, the YoJumbo adapts to any pocket and any hand—ready for heavy utility, range days, and everyday carry alike.

Why the YoJumbo (Black DLC) Belongs in Your Rotation

• Wharncliffe advantage: The long, straight cutting edge and acute tip provide surgical control, crisp scoring, and devastating draw cuts on dense materials.

• Stealth & durability: Black DLC on CPM S30V adds surface hardness, corrosion resistance, and low-signature looks that hide wear and glare.

• Confidence in hand: Textured G-10 scales and sculpted ergonomics provide traction and comfort in wet, sweaty, or gloved conditions.

• Compression Lock® strength: Spine-side lock delivers stout engagement and safe, one-hand closing without crossing the edge.

• Ambidextrous, configurable carry: Round Hole™ opener plus 4-position clip (tip-up/tip-down, left/right) suit any preference.

• USA made: Crafted in Golden, Colorado, with the crisp action and fit Spyderco fans expect.
