Based on custom knifemaker Stuart Ackerman's best-selling Slither design, Spyderco's Sustain is a truly formidable fixed-blade knife. Its broad blade is saber ground from premium CPM 20CV - an advanced particle metallurgy stainless steel renowned for its edge-holding ability and extreme corrosion resistance. An unsharpened swedge on the back of the blade reduces weight and ensures an acute point, while a full tang guarantees optimal structural strength. Contoured, 3-D-machined G-10 handle scales are secured to the tang with concealed pins to offer a clean, extremely comfortable grip and include a generously sized lanyard hole. The Sustain comes complete with a handsome pouch-style leather sheath for convenient belt carry in the field.
