FB23 Aqua Salt

Whether sporting or laboring in saltwater two features rate highly in choosing a fixed blade utility knife, reliable cutting performance and the knife's ability to remain rust free without maintenance. The knife industry toyed unsuccessfully with non-rusting steels for years until two years ago when Spyderco started manufacturing blades using an alloy called H-1. H1 is precipitation-hardened steel, utilizing .1% nitrogen instead of carbon. Carbon is the component in steel that makes the blade hard and allows it to hold an edge. Carbon also reacts to chloride, making rust. With nitrogen replacing the carbon; hardness and edge retention are realized but nitrogen doesn't react to chloride so it physically cannot rust.

Aqua Salt's H-1 blade is thick for hearty use with a weight reducing swedge grind on the spine. It is available fully PlainEdged or SpyderEdged and has a thin, hollow-ground cutting surface. For enhanced visibility the fiberglass reinforced nylon handle is available in cornea searing Marine Yellow or subdued black and comes aggressively textured keeping the knife in your hand even if wet, cold or slippery.[1]


FB23 Aqua Salt Black Blade

Spyderco’s original Aqua Salt was an amazingly versatile, do-everything fixed-blade knife that was also incredibly corrosion resistant. Its legions of die-hard fans ranged from commercial fishermen all the way to military special operations personnel and they were all devastated when it was discontinued. Based on popular demand, the Aqua Salt is now back and better than ever thanks to the addition of a non-reflective titanium carbonitride (TiCN) blade coating. Like the original, it features a broad, hollow-ground blade crafted from H-1® steel—an extraordinary nitrogen-based alloy that is exceptionally tough and ultra corrosion resistant. The blade’s deep hollow grind, drop-point profile, and full-thickness spine provide a superior combination of low-friction cutting performance, point utility, and structural strength.

The handle of the Aqua Salt is made of durable fiberglass-reinforced-nylon (FRN) and is injection molded directly onto the substantial tang for strength. The handle’s Bi-Directional Texturing™ pattern provides a slip-free grip and ensures superior control, even with wet hands. To protect the knife when not in use and allow it to be conveniently carried, the Aqua Salt includes a matching injection-molded polymer sheath with a multi-position G-Clip™ attachment that supports belt or waistband carry. The sheath’s grommeted construction also allows it to be easily lashed or flex-tied to personal equipment. Available with a PlainEdge™ or fully serrated SpyderEdge™ cutting edge, the Aqua Salt is a truly exceptional cutting tool that is now optimized for tactical applications.[2]
