Yes. The KW.INT.1 Blackwash is a Knifeworks exclusive configuration — Pro-Tech built this specific combination of Mardi Gras Camo anodized aluminum handle, Black Lip Pearl button inlay, and blackwash CPM-S35VN blade specifically for Knifeworks. It does not exist in Pro-Tech's standard catalog and is not available at any other authorized dealer. If you see it listed elsewhere, it is either secondary market or a different configuration.

The Mardi Gras Camo is an anodized aluminum finish designed specifically for this Knifeworks exclusive. It draws from Louisiana's Mardi Gras color tradition — purple, green, and gold — rendered in a camouflage pattern that makes each knife visually distinctive. Anodizing is an electrochemical process that converts the surface of the aluminum into a durable oxide layer, so the finish will not chip, flake, or wear the way paint would. The Black Lip Pearl inlay in the button lock adds a natural iridescent element against the camo scales.

The KW.INT.1 uses CPM-S35VN, Crucible's refined iteration of S30V that improved on the original formula with better toughness and edge stability. CPM-S35VN holds a working edge well through daily carry use, resists corrosion in pocket carry environments, and sharpens readily on ceramic or diamond media. The blackwash finish — a tumbled treatment that creates an intentionally weathered appearance — helps conceal the minor scratches and wear marks that accumulate on a blade carried daily.

The Integrity Manual uses Pro-Tech's same build quality, tolerances, and button lock mechanism as their automatic knives, but deploys manually via dual thumb studs rather than a coil spring. This means it carries no automatic knife legal restrictions — it is a standard folding knife legal in all US jurisdictions where folding knives are permitted, and in most international destinations where automatics would be prohibited. The button lock provides the same positive, authoritative lockup found on Pro-Tech automatics.

Yes. The Integrity Manual KW.INT.1 features dual thumb studs — one on each side of the blade flat — allowing fully ambidextrous one-handed opening for both right and left-handed users. No modifications or clip swaps are needed for left-handed deployment, though the clip is configured for right-hand tip-up carry from the factory.

The Integrity Manual KW.INT.1 measures 7.50 inches overall when open with a 3.5-inch blade. Closed length is 5.60 inches. It weighs 4.6 oz. The deep-carry tip-up clip keeps the knife below the pocket line when clipped. The 0.13-inch blade thickness gives the drop point geometry rigidity without adding unnecessary bulk to the carry profile.
