This Spyderco Endura knife has a flat saber-ground VG-10 stainless steel blade with the Emerson Wave opening feature. The handle is blue/gray FRN.
The Endura knife features a molded FRN (fiberglass reinforced nylon) handle with Bi-Directional texturing for traction and improved ergonomics. The handle is strengthened with dual skeletonized stainless steel liners that make an anchor for all external and internal components to attach while adding sturdiness and rigidity. Phosphor bronze bushings on the blade pivot smooth out the open/close action. The pocket clip is four-way reversible for tip-up/down, left- or right-handed carry. The blade is premium VG-10 stainless steel from Seki-City Japan and has Spyderco's easy to use thumb hole for simple, efficient one-hand opening of use the blade-opening feature made popular and patented by Ernest Emerson of Emerson Knives.
The Emerson opening feature is a hook curving out the top of the knife's blade. When removing the knife from a front pocket it catches the pocket's edge quickly opening the knife blade so that it's ready to use. The knife can also be taken out of the pocket without engaging the opening feature by pulling it straight up and out with your fingers on top of the closed blade.
The Endura is a larger version of the Spyderco Delica knife. Both knives have been extremely popular over the years thanks to their lightweight, high performance build and affordable price.
