M9 Bayonet in CS2: Skins, Cases & Prices

Updated 2026-11-11 · 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. It first appeared in the CS:GO Weapon Case (2013) and drops from 16 cases in total. 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.

Which cases have the M9 Bayonet?

The M9 Bayonet drops from 16 cases. In every one of them it shares the rare pool with other knives (Bayonet, Flip Knife, Gut Knife and Karambit), so a knife from these cases is usually not a M9 Bayonet. The table lists every case with the M9 Bayonet finishes it can give and the odds per case opened.

How the odds are calculated: every case gives a knife or gloves 0.26% of the time, and we split that evenly over the different knife finishes in each case's rare pool (counted from the case's item list, with a Doppler or Gamma Doppler counted as one finish whatever its phase), because Valve only publishes the 0.26% total.

Work out your chances over many openings with the CS2 knife odds calculator, check what every M9 Bayonet sells for on CS2 knife prices, or skip the unboxing with a knife trade up using Covert skins from one of these cases.

The case decides which skins you can get: a Doppler or Marble Fade M9 only comes from the cases that list those finishes above.

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. The odds per case are in the table above.

Picking a finish

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