In 1990 Spyderco shook things up by introducing the Endura which was the first of its kind on the market and opened up the knife market to lightweight performance, one-hand open pocketknives that just about everyone could afford. It quickly became one of Spyderco's top sellers and its improvement hasn't slowed since. Refinement has been so ongoing and continual Spyderco tagged the updating/upgrading process with the term CQI- Constant Quality Improvement. During the Endura's CQI journey Spyderco tweaked ergonomics, refined blade steels and fine-tuned its performance countless times. It is an evolutionary work in progress and the next level is here with the new Endura 4.
It now has screw construction making cleaning and adjusting easier. The fibreglass reinforced nylon (FRN) handle comes moulded with Bi-Directional Texturing® for preferred traction and improved ergonomics. Inside the handle dual skeletonized stainless steel liners make the knife stronger without adding weight and make an anchor for all external and internal components to attach through adding sturdiness and rigidity. The VG-10 blade is flat saber-ground with a stronger tip and larger 13mm opening hole. Added to the blade's spine is slip resistant jimping. Phosphor bronze bushings smooth out the open/close action and the clip is upgraded to a four-way tip-up, tip-down, left- or right-handed clip.
