Oversized Precision. Tactical Confidence. A Wharncliffe That Commands Respect.

The YoJumbo is Spyderco’s scaled-up evolution of Michael Janich’s Yojimbo 2 — designed for users who want maximum cutting power and control in a larger format. With a 4" hollow-ground Wharncliffe blade and coarse-textured G-10 handle, this knife delivers tactical performance and ergonomic comfort in one formidable package.

Nested skeletonized stainless liners add strength while minimizing weight, and the Compression Lock provides strong lockup with safe one-handed closing. A four-position clip and Spyderco Round Hole round out a folder built for oversized control and personal-defense readiness. The satin finish keeps the blade clean and low-glare, and the black G-10 handle with coarse texture keeps grip secure in any conditions.
