Spyderco Knives - Yojumbo - 4" Spy27 Steel Folding Knife W/ Cobalt Blue G-10 Handles

Description

The Spyderco YoJumbo SPY27 takes Michael Janich's highly respected self-defense and utility design to the next level. Building upon the success of the Yojimbo 2, the YoJumbo increases the overall size by more than 20%, offering enhanced cutting performance and a handle that comfortably accommodates a wider range of hand sizes.

At the heart of this knife is a formidable 3.98" Wharncliffe blade crafted from CPM SPY27 steel, Spyderco's proprietary cobalt-enriched particle metallurgy stainless steel. Exclusive to Spyderco, SPY27 delivers an exceptional balance of edge retention, toughness, and corrosion resistance. The blade's aggressive Wharncliffe profile excels at controlled slicing and precision cuts, while the deep hollow grind enhances cutting efficiency through a wide variety of materials.

Fast, reliable deployment comes courtesy of Spyderco's iconic Trademark Round Hole, allowing for smooth, fully ambidextrous one-handed opening. The blade locks securely in place with Spyderco's renowned Compression Lock, offering exceptional strength, ease of use, and confidence during demanding cutting tasks.

The handle features skeletonized stainless steel liners nested within textured cobalt blue G-10 scales, a signature color associated with Spyderco's SPY27 lineup. This construction provides excellent strength while keeping weight manageable for a knife of this size. The peel-ply texture ensures a secure grip, and the open-backed design helps reduce weight while making maintenance easy.

A fully ambidextrous four-position pocket clip allows tip-up or tip-down carry on either side, giving users maximum flexibility to configure the knife to their preferred carry style.

Designed and manufactured in the USA, the Spyderco YoJumbo SPY27 is a powerful cutting tool that combines premium steel, proven ergonomics, and one of Spyderco's most recognizable blade designs into a package built for serious everyday carry and hard-use performance.
