Custom knifemaker Stuart Ackerman specializes in extremely practical, incredibly functional designs inspired by his own real-world experience as an avid outdoorsman and a former infantryman in the Angolan Bush War. Based on his best-selling handmade “Slither” model, the Spyderco Sustain is a truly formidable fixed-blade knife that reflects the hard-won insights of its designer.
The Sustain’s 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. A prominent swedge (unsharpened bevel) on the spine of the blade reduces weight and ensures an acute point without sacrificing strength. It also balances the handle’s sturdy, full-tang construction to give the knife an amazingly deft, lively feel in the hand. The handle’s refined shape includes a subtle sub-hilt for enhanced purchase and an understated, but highly effective, integral guard. Its smooth G-10 scales are meticulously radiused and secured to the tang with concealed pins to offer a clean, extremely comfortable grip.
To protect the knife when not in use and provide comfortable, convenient carry in the field, the Sustain comes complete with a handsomely crafted leather pouch-style sheath.
