Description SP122TIBKP: C122TIBKP Tenacious Frame Lock - Titanium Spyderco Designed by Eric Glesser and introduced in 2008, the Tenacious was created to deliver the same convenience, versatility, strength, and cutting performance as Spyderco's other groundbreaking CLIPIT knives, but at a much more affordable price point. The flagship of Spyderco's Value Folder family, it has not only defined the format for other budget-friendly models, but has also evolved to include more refined expressions of its now-iconic design. The inchOG inch Tenacious In its original form, the Tenacious features stout stainless steel liners and an easy-to-clean open-backed construction style. Skeletonized to reduce weight, the liners extend the full length and width of the handle for maximum strength and form the foundation of the knife's sturdy LinerLock mechanism. They are reinforced by peel-ply-textured scales machined from G-10, a lightweight fiberglass-epoxy laminate that offers outstanding strength and a comfortable, secure grip. The blade of the base version of the Tenacious is crafted from 8Cr13MoV stainless steel—a durable, reliable blade steel that provides an excellent balance of cutting performance and ease of sharpening. Its full-flat grind creates exceptional edge geometry for low-friction cutting performance. Unlike most Spyderco folders, its edge also extends the full length of the blade, providing superior control when cutting near the inchheel inch of the blade (closest to the handle). This feature also allows it to inchcut above its weight inch when the full length of the edge is brought into play. To support all carry preferences and keep the knife poised for immediate access, the Tenacious design features a broad-based four-position pocket clip that is easily configured for left or right-side, tip-up or tip-down carry. For duty-bound users concerned with light discipline and those who prefer the aesthetics of an all-black format, the G-10-handled Tenacious is also available with a black oxide blade coating and matching black handle hardware. The Tenacious Lightweight To make the Tenacious even more affordable and versatile, in 2019, Spyderco introduced a lightweight version featuring injection-molded fiberglass-reinforced-nylon (FRN) scales. The molded scales reduce the overall weight of the knife by almost 10 percent compared to the G-10-handled version and add the enhanced grip security of Spyderco's signature Bi-Directional Texture pattern. For tactical end users, the Tenacious Lightweight is also available in all-black configurations with black oxide blade coatings. Steel Upgrades The choice of 8Cr13MoV stainless steel in the original Tenacious and Tenacious Lightweight was a very purposeful one. This calculated compromise allowed the design to remain very affordable while still maintaining extremely high standards of fit, finish, and overall construction. However, as the Tenacious became increasingly popular, fans of the model expressed interest in inchhigh-performance inch versions with more sophisticated blade steels. The responses to that calling included a Tenacious Lightweight that proudly features CPM S35VN stainless steel and a G-10-handled version featuring CPM M4 tool steel. These premium, American-made powder metallurgy steels offer a significant performance enhancement over 8Cr13MoV and ushered in a new era of the evolution of this workhorse design. The Tenacious R.I.L. Throughout its evolution, the Tenacious steadily earned a reputation that transcended its budget-friendly roots to establish it as one of the cutlery industry's truly iconic designs. To celebrate that achievement, Spyderco decided to raise the bar even higher. Many knife enthusiasts regard the Reeve Integral Lock (R.I.L., or inchframe lock inch) popularized by legendary custom knifemaker Chris Reeve to be the next-level improvement of Michael Walker's LinerLock. True to that spirit, Spyderco has created a R.I.L. expression of the Tenacious that represents the next phase in its design evolution. The Tenacious R.I.L. elevates the knife's classic design with the addition of titanium handle scales and an ultra-reliable R.I.L. mechanism. Painstakingly crafted from solid 6AL-4V titanium, the scales have precision-machined recesses on their interior surfaces that remove material while creating a reinforced web-like structure. This complements the handle's easy-to-clean, open-backed construction to minimize the knife’s weight and optimize its balance in the hand. The reverse-side scale is machined to create an integral lock bar that forms the basis of the knife's R.I.L. mechanism. The end of the lock bar houses an inlaid stainless steel interface that provides a long-wearing steel-to-steel contact point. This feature not only ensures positive lock engagement, smooth operation, and a long service life, but also functions as an overtravel stop to prevent overflexing of the bar’s spring action during lock release.
