The INQUISITOR Stonewash Blade

We designed this knife for strength without limits. The INQUISITOR is built as a full-tang (single-piece steel construction) with a fixed blade. This solid piece of steel guarantees unmatched durability and reliability—no matter the stress, no matter the environment. When the stakes are high, this blade doesn’t flinch.

Crafted from durable 1.4116 stainless steel, the INQUISITOR boasts a 5 mm thick profile and a Rockwell hardness of 57 HRC. That’s the sweet spot: tough enough to hold a razor-sharp edge through repeated use, yet resilient enough for easy touch-ups in the field.

Meanwhile this dagger features a single sharpened edge with a non-sharpened false edge on the reverse side.

Moreover, finished in a rugged stonewash, the blade wears its grit with pride. This stealthy treatment cuts glare, camouflages wear, and reinforces the knife’s tactical edge — all while enhancing its brutal elegance.

⚠️ Note: According to the conclusion of the Ministry of Internal Affairs of Ukraine, this dagger has a single edge and a false edge on the other side. Please ensure you use the sharpened side of the blade when cutting.
