Updated at 01:01 UTCListed on 5 of 8 markets · 69 offersOffer counts show how many copies are for sale, not how many have sold. A market with only a few offers can have its price set by a single listing. Each row shows how far it sits above the cheapest price, and “price only” means the market shows a price without a link. The wear tiles and the table by wear also count Steam listings, so their offer counts run higher.

★ M9 Bayonet | Case Hardened: collection and crates

This is the M-9 bayonet. Originally intended to be mounted on a rifle, it is also well suited to close-quarters combat. It has been color case-hardened through the application of wood charcoal at high temperatures. A little color never hurt anyone
