Custom knifemaker Stuart Ackerman is a South African native who currently lives in New Zealand. A veteran of extensive military combat service, he knows from harrowing personal experience what a knife really needs to do in the field and incorporates that real-world insight into every one of his designs, including the Spyderco Sustain G-10 Plain Fixed Blade Knife.

Ackerman originally designed the Sustain to meet the needs of a group of daring sportsmen who hunted wild pigs with only a knife and a small pack of dogs. He also wanted it to be a highly functional all-purpose cutting tool well suited to 'sustaining life' by helping to make fire, build shelter, and prepare food

The heart of the Sustain is its broad six-inch blade, which features a sturdy saber grind and a long swedge (unsharpened back bevel). It is expertly crafted from Crucible CPM-20CV—an advanced particle metallurgy stainless steel that contains a high volume of chromium and vanadium. This potent combination gives it a remarkable combination of high wear resistance, superior corrosion resistance, good impact toughness, and excellent polishability.

For maximum strength, the Sustain features full-tang construction capped by contoured, polished G-10 scales that are secured by blind pins. The handle’s ergonomic profile includes a substantial integral guard and subhilt to protect the user’s hand from sliding forward, a flared butt to maintain positive control when chopping, and a large lined lanyard hole for easy attachment of safety cords or lanyards. A handsome traditional leather pouch-style sheath completes the package and allows convenient carry on the belt.

Pros:

• Durable CPM-20CV steel with excellent wear and corrosion resistance.
• Versatile blade design suitable for heavy-duty tasks like chopping and slicing.
• Full-tang G-10 handle provides a secure, ergonomic grip with added safety features.
• Designed with real-world functionality for survival and hunting.
• Includes a high-quality leather sheath for convenient carry.

Cons:

• Slightly heavy at 7.3 oz., which may not suit all users.
• Requires regular maintenance to maintain peak performance.
