The relic texture is a deliberately aged surface treatment applied to the black anodized aluminum handle scales — a process that creates visible variation in the anodize with worn, distressed areas that give the handle an organic, carried appearance from day one. No two relic finished handles are identical — the variation in the aging process means each knife has a unique surface character. The relic finish is distinct from standard smooth or bead-blasted anodize: it reads as a knife that has been somewhere, even when new.

The INT106 uses CPM-S35VN with a DLC black coating. CPM-S35VN is Crucible's refined iteration of S30V that improved toughness and edge stability while maintaining the corrosion resistance and edge retention that made S30V the benchmark production EDC steel. The DLC coating adds a further layer of surface hardness on top of S35VN's base performance, making the blade more resistant to abrasion and surface wear through daily carry while eliminating glare.

No. The Integrity INT106 is a manual folder — it deploys via double thumb studs on both sides of the blade flat with no spring or coil mechanism. It is legal in all US jurisdictions where folding knives are permitted and in most international destinations where automatic knives would be prohibited. No compliance form is required at checkout. The button lock provides the same positive, authoritative lockup found on Pro-Tech's automatic lineup.

Yes. The INT106 features double 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 Knifeworks exclusive Integrity variants (KW.INT.1 Blackwash and KW.INT.1 BLACK) both feature the Mardi Gras Camo anodized aluminum handle specific to Knifeworks. The INT106 is a standard Pro-Tech production Integrity with a relic textured black anodized handle — available through authorized dealers generally. All three share the same CPM-S35VN blade steel, manual thumb stud deployment, button lock, and overall dimensions.

The Integrity INT106 measures 8.0 inches overall when open with a 3.5-inch blade at 0.125 inches thick. Closed length is 4.50 inches. It weighs 3.8 oz. The tip-up right-hand clip is included for pocket carry.
