In 1990 Spyderco shook things up by introducing two knives, the Delica and Endura. First of their kind on the market, both folders opened up the knife market to lightweight performance, one-hand open pocket knives that just about everyone could afford. They settled as our top two bestsellers and their improvement hasn't slowed since.

We've always taken great pride in our efforts to push the envelope of performance by offering exotic blade steels in our knives. With that spirit in mind, we are proud to offer the Endura 4 Lightweight with a blade crafted from K390. 

Manufactured by Böhler-Uddeholm, K390 MICROCLEAN® is a state-of-the-art cold work tool steel produced by the particle metallurgy process. Its advanced alloy mix was specifically developed to provide the extreme wear resistance and high compressive strength needed in industrial cutting, blanking, and punching operations. Despite its toughness, its exceptionally fine, homogeneous microstructure also makes it readily machinable and easy to heat treat. 

Collectively, these qualities make K390 an outstanding blade material for true steel connoisseurs.

    Great Steel

    Posted by Ken Neal on 4th Jan 2021

    K390 is an awesome steel! Knife came razor sharp and the action is smooth with no blade play. The only gripe I have is the blade is off center which seems to be happening more often with Spyderco plastic handle knives. Other than that it’s a great knife especially for hard use.

    K390 Endura

    Posted by Tucker on 4th Dec 2020

    I was very excited to see that Spyderco was making an Endura in K390, my favorite steels are 10V class steels, these are run a lot harder than the Pm2 from bento box from what I’ve heard these are around 65Hrc, the knife was an excellent specimen and everything was what I wanted. Definitely would recommend REC, one of the places to buy knives!
