The SGIAN DUBH Premium from Blade Brothers Knives is a compact, lightweight fixed‑blade knife inspired by the legendary Scottish sgian dubh. Part of our historical lineup, it carries centuries of proven design that still feels relevant today. Traditionally worn discreetly in a stocking or sleeve, the sgian dubh served as a hidden ally in critical moments — a symbol of honor and readiness.
We handcraft the SGIAN DUBH Premium from Austrian Böhler N690 stainless steel, forged in a heavy‑duty 4.5 mm full‑tang construction. Moreover, сobalt alloying gives this steel aggressive cutting power, long‑lasting edge retention, and, as a result, strong resistance to corrosion. Our craftsmen make every knife by hand, blending heritage tradition with modern performance.
We carry out the entire heat‑treating process in‑house, including both thermal cycling and cryogenic treatment with liquid nitrogen. As a result, we bring the steel to an optimal hardness of 59–60 HRC. In addition, cryogenic processing refines the grain structure, which in turn boosts toughness and reduces the risk of chipping under heavy use.

The handle flares outward near the blade, forming a natural guard that keeps your fingers safe and prevents slipping onto the edge. Textured Richlite scales deliver a secure, confident grip — even in wet conditions.
Each knife comes with a rugged plastic sheath fitted with a steel clip that’s fully MOLLE‑compatible. Finally, we space the sheath eyelets to fit a TEK LOK mount, giving you flexible carry options for both tactical setups and everyday use.
The SGIAN DUBH Premium is a discreet everyday carry knife built for functionality, reliability, and comfort. Compact and lightweight, it’s ideal for urban tasks and can serve as a dependable option for self‑defense.
