The mid-sized Spyderco Tenacious Knife has a black G-10 laminate handle that is milled for traction. Tucked inside are skeletonized steel liners increasing the handle's rigidity and strength without adding non-functioning weight or bulky thickness. The Tenacious features a leaf-shaped stainless blade that is ground flat from spine to cutting edge for cutting performance. 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.
