Ostap Hel

Arbiter Premium | M390 | Fixed | Micarta

$199.00USD $255.00

With a total length of exactly 230mm, the Arbiter is by far one of the largest knives ever designed and created by RSK and Ostap Hel. The blade itself is extremely long full flat grind, that looks truly beautiful. A true standout design feature is the expertly crafted round back along the back of the knife.

The blade is made from M390 that has undergone cryogenic treatment, giving the knife extra durability and sharpness. Another staple of this RSK and Ostap designs is the hidden lanyard hole at the back end of the handle.

This small feature allows for greater carrying while at the same time not protruding and effecting the overall design. The attaching of a lanyard also give this knife greater cutting options as the hand can be placed further down the handle.

To keep control of all of this weight and strength, micarta handles have been fitted onto the knife coming it at around 7mm each. As well as this the Arbiter comes with a standard Kydex sheath that locks the knife firmly in place.


The Arbiter Premium, a collaborative design by RSK and Ostap Hel, exemplifies a fusion of tactical performance and refined craftsmanship.
