The Spyderco Endura 4 in cobalt blue is a full-size lockback folder, one of Spyderco's most proven designs, here upgraded with a premium American blade steel. The 3.88" CPM S35VN stainless blade arrives in a satin finish -- S35VN is a high-end American powder metallurgy stainless steel developed for superior edge retention, toughness, and corrosion resistance. The cobalt blue FRN handle features Spyderco's bi-directional texture for a secure grip in any direction, while keeping the knife remarkably lightweight, in a 5" closed package backed by a reliable lockback mechanism. Spyderco's signature thumb pull makes one-handed opening straightforward, and a lanyard hole plus pocket clip round out the carry options.
