The Spyderco Sage 5 Salt C123GPBKMCBK is the fully blacked-out version of the most capable marine EDC folder Spyderco has produced — CPM MagnaCut steel under a TiCN Black coating, all-black G-10 handle, and the Compression Lock, in a build that eliminates every reflective surface and adds a second layer of corrosion protection on top of an already saltwater-ready steel.

The CPM MagnaCut blade is Larrin Thomas's purpose-engineered powder metallurgy steel, designed to outperform every production EDC steel on edge retention, toughness, and corrosion resistance simultaneously — the combination that makes it the right steel for a Salt series build. The TiCN (Titanium Carbonitride) Black coating elevates that already strong corrosion resistance further: TiCN is a physical vapor deposition coating harder than most tool steels, chemically inert against salt, moisture, and acid, and bonded directly to the blade flat at the molecular level rather than sitting on top of it. Where Cerakote is a polymer-ceramic coating, TiCN is a true hard coating that adds measurable surface hardness to the blade while reducing friction and eliminating glare completely. On CPM MagnaCut, the TiCN coating means this blade is essentially impervious to saltwater corrosion under real-world marine carry conditions — the steel handles it from the inside, the coating handles it from the outside. The full flat grind behind a 3.00-inch drop point produces a thin slicing geometry that cuts well above the knife's compact size.

• Blade: CPM MagnaCut, full flat grind, drop point profile, TiCN Black coating — purpose-engineered PM steel with M390-class edge retention and saltwater-worthy corrosion resistance; TiCN hard coating adds surface hardness, chemical inertness, and zero-glare appearance independent of the steel's own corrosion properties
• Handle: Black G-10, textured for positive grip in wet conditions, full Sage 5 ergonomics with no hot spots — G-10 is impervious to moisture, salt, and temperature variation; all-black construction eliminates every reflective or contrasting element for a fully stealth build
• Deployment / Lock: Spyderco Round Hole thumb opening, Compression Lock — the Compression Lock leaf spring engages the blade tang from the spine rather than the scale, making it ambidextrous and one of the strongest lock geometries in production folders; lateral blade pressure increases lock engagement rather than working against it
• Carry: 3.17 oz, tip-up right-hand clip, 4.27 inches closed — full-size carry weight in a compact 3-inch blade package; lanyard hole present for tethered deck or water carry

Ideal For

Saltwater anglers, divers, and boaters who need a fully blacked-out marine folder with no reflective surfaces — the TiCN Black coating eliminates glare on the blade flat that a satin or stonewash finish would create on the water, and the all-black G-10 handle completes a build with zero light signature. Buyers choosing between the two Sage 5 Salt MagnaCut variants who want maximum corrosion protection — the TiCN coating adds a hard chemical barrier on top of CPM MagnaCut's own corrosion resistance, making the C123GPBKMCBK the more protective build of the two for sustained saltwater exposure. Tactical and low-profile EDC buyers who want a corrosion-resistant folder for daily carry without the high-visibility yellow handle of the standard Salt colorway — the C123GPBKMCBK delivers the same steel and lock in a completely subdued all-black package.

CPM MagnaCut under TiCN Black, Compression Lock, all-black G-10, and Salt series construction built for the worst environments a folder encounters — the Spyderco Sage 5 Salt C123GPBKMCBK is the most corrosion-protected production EDC folder in the Knifeworks catalog.
