The ★ M9 Bayonet | Rust Coat is a Covert knife skin in Counter-Strike 2, available since January 2015 from the Chroma Case.

The float range for this finish is restricted to 0.40–1.00, so Well-Worn and Battle-Scarred are the only obtainable conditions on the open market. Factory New examples are not produced for this skin — even the cleanest copies will show some surface texture.

A StatTrak™ version is available, which tracks confirmed kills made while the skin is equipped and typically commands a premium over the standard finish. Active listings for ★ M9 Bayonet | Rust Coat are tracked across 18 marketplaces, with prices spanning $342.50 to $1,165 depending on wear, variant, and seller.
