The Spyderco Endura launched in 1990 side by side with the Delica, and it took Blade Magazine's Overall Knife of the Year that same year. Together they put the Round Hole and pocket clip into a lightweight folder a working man could afford, and both have sat near the top of Spyderco's sales for more than three decades. Four generations of Constant Quality Improvement later, the Endura 4 is built in Seki City, Japan, and our Spyderco history tells the full story.
The Endura 4 carries a 3.8 inch VG-10 blade with a full flat grind at .118 inch stock, giving you real reach for cardboard, rope, food prep, and utility work. A 13mm Round Hole opens it with either hand, even in gloves or with cold fingers. Bi-Directional Texture on the FRN scales keeps the grip locked in, and the longer handle fills larger hands. It runs 8.78 inches open, 4.98 closed, and 3.3 ounces.
A refined back lock on the spine releases with a press of the rocker and has proven itself across millions of Enduras. The four position clip carries tip up or tip down on either side. Our guide to knife lock types covers why the back lock is still trusted.
VG-10 is the standard, and sprint runs and exclusives move up to K390 and SPY27, plus a Damascus blade with titanium scales. Our comparison of every major knife steel lays out what each upgrade gets you.
The Endura comes in plain, partially serrated, and fully serrated edges, a Wharncliffe blade, a Wave opening version that deploys on the draw, stainless steel handles, and a trainer, across a full color lineup. It is the pick for anyone who finds the Delica a size short but wants to stay slim and light. For more blade still, the Military is the next step up in the Spyderco lineup.
