Updated 2026-09-25 ยท Knives

Which cases have the M9 Bayonet, which finishes you can get from each, and the cheapest way to own one.

What is the M9 Bayonet?

The M9 Bayonet is a military-style fixed blade with a slightly curved spine and a smooth, heavy inspect animation. Like every knife it only exists as a rare special item: it drops from a handful of cases or comes out of a Covert-to-knife trade up.

How to get a M9 Bayonet

  • Buy it: the cheapest way to get a specific finish and float.
  • Knife trade up: five Covert skins from one of the cases above give a random item from that case's pool, which may or may not be a M9. Check the odds in the knife trade up calculator.
  • Unbox it: about 0.26% per case for any knife, and the pool is shared with other knives, so this is the most expensive route on average.

Picking a finish

Budget finishes (Safari Mesh, Boreal Forest, Scorched, Forest DDPAT, Urban Masked) are the cheapest way into a M9. Fade, Doppler, Marble Fade, Case Hardened and Crimson Web sit at the top, and specific phases or patterns can multiply the price. More in the most expensive CS2 knives and the cheapest CS2 knives.
