Sandvik 14C28N and Vacuum-Cryogenic Treatment
The blade is made of Sandvik 14C28N steel, hardened to 60–62 HRC. Vacuum hardening combined with cryogenic treatment was used, which promotes high hardness, wear resistance, and stable steel properties during regular use.
Drop Point, flat grind, and Bead Blasted
The Drop Point profile provides versatile functionality and good tip control. The flat grind facilitates smooth cutting through materials, while the bead-blasted finish gives the blade a matte, technical appearance.
Yellow Ultem, Full Tang, and Kydex
The handle is made of yellow Ultem and mounted on a Full Tang construction, in which the blade tang extends the entire length of the handle. The grips are secured with bead-blasted steel screws.
The knife comes with a black Kydex sheath. The set also includes a TEK-Lok, which allows for convenient attachment of the sheath to a belt or other gear.
