Since its debut in 2011, Michael Janich's Yojimbo 2 design has carved out a prominent place in Spyderco's lineup, amassing a dedicated global following. Building upon this success, the YoJumbo expands on the original by increasing its size by over 20%, enhancing ergonomics to accommodate a broader range of hand sizes. The YoJumbo features a robust four inches (102mm) Wharncliffe blade, hollow ground to ensure optimal edge geometry. It includes a fully accessible Trademark Round Hole, enabling swift, ambidextrous, one-handed opening. The handle's open-backed design and nested, skeletonized stainless steel liners reduce weight, while its textured G-10 scales provide a secure, non-slip grip. Equipped with a robust Compression Lock and a versatile four-position pocket clip, the YoJumbo is tailored as an exceptional cutting tool ideal for personal-defense carry.
