Product Description
The Spyderco YoJumbo takes Michael Janich’s popular Yojimbo 2 design and scales it up for users who want a larger, more hand-filling tactical folder. Its broad Wharncliffe blade delivers outstanding cutting power, with a deeply hollow-ground edge that excels at controlled slicing and utility work.
This model uses Spyderco’s proprietary CPM SPY27 blade steel, a cobalt-enriched particle-metallurgy stainless steel made exclusively for Spyderco. It offers an excellent balance of toughness, edge retention, and corrosion resistance. The blade opens quickly with Spyderco’s Trademark Round Hole, while the Compression Lock provides strong, secure lockup.
The handle features cobalt blue peel-ply textured G-10 scales over skeletonized stainless steel liners for a sturdy yet weight-conscious build. A four-position pocket clip allows tip-up or tip-down carry on either side, making the YoJumbo easy to configure for right- or left-handed users.

About brand
Quick! List the most respected and innovative knife companies you can think of. If you know anything about knives, Spyderco is somewhere near the top. Spyderco Inc. makes some of the most unique and downright bizarre knife designs you'll see on the market, but from the number of passionate fans discussing, debating, and learning everything they can about Spyderco knives, it's clear that the company has done something right.
From the Glesser Family and the Spyderco Crew:
Since starting Spyderco we've been told our knives are different, peculiar, even out there. All true. Thinking beyond established knife industry barriers allowed us to introduce new and radical innovations to the knife culture including: One-hand opening, serrations on a folder and a clip to attach a knife to a pocket.
We didn't go into business to rake in a mountain of dough we're here for more selfish reasons- indulging our passion for creating knives. Spyderco is definitely out of the norm in the knife industry in our dedication to researching and developing fresh, improved and better performing materials all with function and reliability being key.
Someone once said to Sal Glesser, Spyderco's owner, 'You must design in the dark because your knives look so strange.' True again. Our recognizable appearance is a result of designing ergonomic functional tools rather than applying lipstick and nylons to a pocketknife. We may look curious, homely, whatever, but we'll never be called unusable or undependable.
Making knives that consistently deliver reliable high-performance requires an ongoing commitment to testing. In our million-dollar testing facility we examine edge retention with a CATRA machine, look for rust development with Q-FOG, check the force needed to open and close a knife. We also repeatedly test for stress, wear, optimal heat-treating and actively search for higher quality, performance enhancing steels and materials.
As a customer you probably don't think about this, or much care, but it allows us to put forth a promise. When you purchase a Spyderco you are buying a high-quality reliable cutting tool designed and manufactured for peak performance and ergonomic comfort. Those Who Know Carry Spyderco.
