- — Description
It is only available through completing the Omsk Hammer bounty collection in the Depot. The Omsk Hammer is functionally identical to the Knife. However, unlike the Knife, the Omsk Hammer can be equipped in a matter similar to that of the Combat Knife featured in previous installments. The Omsk Hammer resembles that of a worker's hammer.
- The hammer's name refers to a town called Omsk in Siberia, which served as the capital of the anti-Bolshevik Russian State.
