Proudly offering all the features and benefits that define a Spyderco knife in a budget-friendly package, the Tenacious has long been the centerpiece of Spyderco's Value Folder line. The Tenacious Lightweight raised the bar even further, replacing the original G10 scales with injection-molded fiberglass-reinforced nylon (FRN) that reduces the knife's weight by almost 12 percent and adds the extreme grip security of Spyderco's Bi-Directional Texture pattern.
