Supercharged Endura
In 1990, Spyderco revolutionised the knife industry with the introduction of two groundbreaking models: the Delica and Endura. These pioneering folding knives were the first of their kind to offer lightweight, one-hand-opening designs at an affordable price point, quickly becoming our top two bestsellers. Since their launch, both models have seen continual improvement, maintaining their reputation for exceptional performance.
"A 3.78" Wharncliffe in K390?! Savage." - Mr. Narwhal 
Continuing our tradition of pushing the boundaries of blade performance, we are thrilled to present the Spyderco Endura 4 Lightweight featuring a blade crafted from premium K390 steel.
Manufactured by Böhler-Uddeholm, K390 MICROCLEAN® is a state-of-the-art cold work tool steel produced through the particle metallurgy process. Developed with a specialised alloy mix, K390 offers exceptional wear resistance and high compressive strength, making it ideal for industrial applications such as cutting, blanking, and punching. Despite its remarkable toughness, K390’s fine, homogeneous microstructure ensures that it is easy to machine and heat treat, making it a versatile and high-performance blade material.
With these remarkable properties, K390 is an outstanding choice for true steel enthusiasts who demand top-tier performance from their knives.
