The Spyderco YoJumbo SPY27 builds on Michael Janich's acclaimed Yojimbo 2, scaling it up for greater cutting capability and improved ergonomics. Designed to suit a wider range of hand sizes, it combines control, strength, and cutting performance in a robust everyday-carry folder.
Its distinctive Wharncliffe blade is precision ground from Spyderco's exclusive CPM SPY27 stainless steel. Developed specifically for Spyderco, this cobalt-enriched powder-metallurgy steel offers an excellent balance of edge retention, toughness, and corrosion resistance for demanding daily use.
The deep hollow grind maximises cutting efficiency while maintaining excellent edge geometry for clean, controlled cuts. Spyderco's Trademark Round Hole™ enables fast, fully ambidextrous one-handed opening for quick, reliable deployment.
The open-backed handle is built around skeletonised stainless steel liners that reduce weight without compromising strength. These liners support Spyderco's renowned Compression Lock, delivering lock strength alongside smooth, safe one-handed operation.
Finished with peel-ply textured cobalt blue G-10 handle scales, the YoJumbo provides outstanding grip and comfort in all conditions. The blue scales also identify the knife as part of Spyderco's exclusive CPM SPY27 range.
A four-position pocket clip offers flexibility, allowing left- or right-handed carry in either tip-up or tip-down configurations, making the YoJumbo adaptable to virtually any carry preference
