The Spyderco Endura 4 Lightweight Folding Knife with a K390 blade is engineered for high-end performance and durability, making it an ideal choice for demanding tasks. K390 MICROCLEAN is a top-tier cold-work tool steel designed for exceptional wear resistance and compressive strength, which makes the Endura 4 highly effective in industrial and precision cutting tasks. This knife is built for longevity and reliability, boasting a stonewashed finish that enhances the blade’s resilience while maintaining a sleek, practical appearance.

Key Features:

  • K390 MICROCLEAN Blade: The 3.80" blade is made from K390 steel, a premium tool steel developed for extreme wear resistance and strength. The fine, homogeneous microstructure offers excellent edge retention and machining properties.
  • Stonewashed Blade Finish: The blade is stonewashed for an aesthetically appealing and functional finish. The stonewash treatment reduces the appearance of scratches and wear, ensuring the blade looks good for longer while maintaining excellent cutting performance.
  • Full-Flat Blade Grind: The blade features a full-flat grind, which minimizes friction and maximizes cutting efficiency. The grind ensures precision cutting with minimal drag, making it a versatile tool for a wide range of cutting tasks.
  • Plain Edge: The knife features a plain edge, providing clean and accurate cuts, ideal for general-purpose tasks and precision work.
  • Lockback Mechanism: The Endura 4 utilizes a lockback mechanism that securely locks the blade in place while in use. This lock provides stability during tasks while ensuring the knife can be easily closed with one hand when finished.
  • Lightweight Construction: Despite its high-performance blade, the Endura 4 is remarkably lightweight, weighing only 3.30 oz. This makes it perfect for daily carry without sacrificing cutting power.
  • Ergonomic Handle: The lightweight FRN handle is designed for a comfortable, non-slip grip. It also features Spyderco’s signature Bi-Directional Texturing, which enhances control and prevents slipping even in wet or challenging environments.
  • Four-Position Pocket Clip: The four-position hourglass pocket clip allows you to carry the knife according to your preference, supporting both left- and right-side tip-up or tip-down carry for maximum convenience.
