Both are Knifeworks exclusive Integrity Manual configurations with the same Mardi Gras Camo anodized aluminum handle, CPM-S35VN blade steel, manual dual thumb stud deployment, and button lock. The difference is the blade finish. The KW.INT.1 Blackwash uses a tumbled blackwash treatment that creates a mottled, weathered appearance with tonal variation across the blade flat. The KW.INT.1 BLACK uses a Black PVD finish — a vapor deposition coating that bonds uniformly to the blade surface for a clean, consistent matte black with no tonal variation. PVD is more durable and wear-resistant than blackwash. The BLACK variant is priced at $320.00 versus $270.00 for the Blackwash, reflecting the cost difference of the PVD process.

Yes. The KW.INT.1 BLACK is a Knifeworks exclusive — Pro-Tech built this specific combination of Mardi Gras Camo anodized aluminum handle and Black PVD 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.

Both PVD (Physical Vapor Deposition) and DLC (Diamond-Like Carbon) are applied through vapor deposition processes that bond the coating to the blade surface at the atomic level. The key difference is the coating material. DLC uses carbon-based compounds that produce an extremely hard surface layer — among the hardest coatings available for knife blades. PVD is a broader category that can use various materials including titanium nitride, chromium nitride, and others, typically producing a durable, corrosion-resistant coating with good adhesion. Both are significantly more durable than anodizing or paint. The Black PVD on the KW.INT.1 BLACK is a Pro-Tech production specification coating applied for corrosion resistance and uniform black appearance.

The KW.INT.1 BLACK 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 Black PVD finish adds a further layer of corrosion resistance and wear protection on top of an already capable stainless steel.

Yes. The Integrity Manual KW.INT.1 BLACK 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 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 BLACK 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. At 0.13 inches of blade thickness the drop point geometry carries the rigidity required for a working knife without adding bulk to the carry profile.
