The mid-sized Tenacious has a black G-10 laminate handle, milled with prolonged fatigue-free cutting in mind. Tucked inside are skeletonized steel liners increasing the handle's rigidity and strength without adding non-functioning weight or bulky thickness. The blade's shape coupled with an oversized Spyderco Round Hole and textured spine jimping allow you to open the blade and position your thumb on the spine in slip-proof confidence ready for work. A Walker Linerlock (with jimped liner) and a 4-way pocket clip lets you set your carry and draw preference: Tip-up/tip-down left-hand/right-hand. Screw together construction.
