The Spyderco Enuff Sheepsfoot Salt CFB31SY is the compact corrosion-immune fixed blade for marine, water rescue, and dive carry — H-1 nitrogen-alloyed steel in a 2.75-inch sheepsfoot profile with a full serrated edge, Yellow FRN handle, and the fixed blade rigidity that no folding Salt knife can match, in a platform purpose-built for one-hand deployment and immediate cutting action when rope, line, or webbing needs to be cut fast in any water environment.

The H-1 blade is a nitrogen-alloyed precipitation-hardened steel that is virtually carbon-free — functionally immune to corrosion in saltwater, marine, and high-humidity environments where every other steel in this session, including LC200N and CPM MagnaCut, will eventually show surface oxidation under sustained exposure. In a fixed blade dedicated to water rescue, diving, and marine carry where the knife may spend extended periods submerged, clipped to dive gear, or stored wet in a PFD pocket, H-1's absolute corrosion immunity is the primary specification — the blade that cannot rust is the right choice for a dedicated rescue tool that must perform reliably after months of marine carry without maintenance. The sheepsfoot blade profile is the safety-first geometry for marine rescue — a straight cutting edge that runs the full usable length of the blade, paired with a flat spine that curves downward near the tip rather than maintaining a point, creating a blade with no piercing tip that eliminates accidental puncture risk during close-quarters cutting in rescue situations where contact with a diver, patient, or casualty is possible. The full serrated edge maximizes the sheepsfoot blade's line-cutting capability — serrations cut through rope, webbing, fishing line, and cordage faster with less effort than plain edge in the push-cutting action that rescue situations demand, and H-1's hardness maintains serration point geometry longer than softer steels in sustained rescue use. The Yellow FRN handle is the highest-visibility color in any underwater or marine environment — located instantly when the knife is needed and provides a positive, secure grip with the bidirectional texture pattern that Spyderco applies to FRN handles for wet-hand use.

• Blade: H-1 nitrogen-alloyed steel, sheepsfoot profile, satin finish, full serrated edge — virtually carbon-free nitrogen alloy with functional corrosion immunity in saltwater and marine environments; sheepsfoot eliminates piercing tip to prevent accidental puncture in close-quarters rescue cutting; full serrated edge cuts rope, line, and cordage faster with less effort than plain edge in rescue push-cutting applications
• Handle: Yellow FRN (fiberglass-reinforced nylon), textured bidirectional grip, compact Enuff profile — FRN is chemically inert and unaffected by saltwater, UV, and marine biological exposure; Yellow is the highest-visibility color in any marine or underwater environment; compact profile fits PFD pocket and dive rig clipping
• Construction: Fixed blade — no pivot, no lock, no mechanism; blade deploys instantly without any opening action required; fixed blade rigidity eliminates any risk of closure under the lateral force of rescue cutting; sheath included for carry
• Carry: Fixed blade marine carry with sheath — designed for PFD chest pocket, belt carry, and dive equipment attachment; compact Enuff profile fits marine carry formats that larger fixed blades cannot

Ideal For

Divers, water rescue personnel, PFD carry buyers, and kayakers who need a dedicated compact fixed blade line cutter with absolute corrosion immunity — the CFB31SY's H-1 steel, sheepsfoot geometry, full serrated edge, and fixed blade construction combine to produce the most purpose-built compact marine rescue cutting tool in the Spyderco Salt lineup, in a package compact enough to fit any PFD pocket or clip to dive gear without adding meaningful bulk. Buyers who carry folding Salt knives as primary marine EDC and want a dedicated fixed blade rescue cutter as a secondary — the Enuff's fixed blade construction deploys instantly without any opening mechanism, making it faster to access under stress than any folding knife, and its compact sheepsfoot serrated configuration is purpose-built for the single task of cutting rope and line in emergencies. Spearfishing and freediving buyers who need a compact H-1 fixed blade sheathed on a dive belt or BCD — the Enuff's compact profile and H-1 corrosion immunity make it the right fixed blade for buyers who carry their rescue cutter on dive equipment where a longer fixed blade would be impractical and a folding knife would be too slow to deploy under water.

H-1 steel that cannot rust in any marine or saltwater environment, sheepsfoot geometry that eliminates accidental puncture risk in close-quarters rescue cutting, full serrated edge that cuts rope and line faster than plain edge in push-cutting rescue applications, Yellow FRN that is found instantly in any underwater situation — and the fixed blade rigidity and instant deployment that no folding Salt knife can match — the Spyderco Enuff Sheepsfoot Salt CFB31SY is the compact corrosion-immune marine rescue fixed blade at $160.
