The stainless-steel-handled Endura combines all the proven features and benefits of this iconic design with the heft and increased strength of a stainless handle. Its blade is saber-ground from premium VG-10 stainless steel and proudly features Spyderco's Trademark Round Hole for quick, reliable one-handed opening. The blade is supported by a sturdy back lock mechanism that locks it securely open when in use. Its satin-finished handle is chamfered at the edges for added comfort and includes four sets of mounting holes for the hourglass clip to support left or right-side tip-up or tip-down carry.
