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 G10 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.

Sleek and Functional Blade
The Sustain is very light and thin. Two things I actually prefer when using a knife outdoors. I've done a few bushcraft tasks with this blade (made a friction fire set, carved a few deadfall traps, and harvested natural materials for cordage making) and it did well at all those tasks. I was drawn to this particular knife as I'd handled similar custom knives while in New Zealand that are used in hunting wild boar on the islands. The Sustain is along those same lines, and could easily fulfill that role as well as doing any other knife tasks you'd have to perform while out in the bush.

Favorite using knife
Love the lines, reminds me of a classic Mediterranean style knife. Long & lean, it is functionally somewhere between a kitchen knife & a dirk with some fillet dna thrown in. I also really like full pouch sheaths. I use it for kitchen duty at home and everything short of chopping in camp. $35 hatchet for that.It will slice tomatoes thin enough to see through. 20cv takes effort to sharpen, but it takes a scalpel edge. Holds a usable edge for a week long trip, no problem. Strop it occasionally. Use spyderco sharpener, works well. This is a great package for me, but is thin & not entirely forgiving. Some folks use knives in such a way that they require a 5mm spine & a hatchet edge grind or the blade is doomed. Not the knife for those guys. But it has taken over my kitchen & forestry service satchel.
