The Persistence® Lightweight combined the compact size and proven features of this time-tested design with the weight-saving advantages of injection-molded fiberglass-reinforced-nylon (FRN) scales. This version takes that evolution a step further, supercharging its performance with American-made CPM® S35VN™ blade steel. The unique chemistry of this steel promotes the formation of niobium carbides along with vanadium and chromium carbides, enhancing its toughness without sacrificing wear resistance. The full-flat-ground blade of this knife is available in all three edge configurations and is paired with a handle featuring bright blue FRN scales, non-slip Bi-Directional Texturing™, a sturdy LinerLock mechanism, and a versatile four-position pocket clip. Notes The Chinese Spydercos all offer excellent value for their price point. From time to time, I carry my Tenacious or Persistence or even Resilience and find myself impressed with the build quality and cutting performance since the blades are ground quite well. If you want a reliable, well designed and built workhorse and you don't mind sharpening, this would be perfect for you!
