About the M9 Bayonet
The M9 Bayonet is one of the original knives in Counter-Strike. It was added to CS:GO in August 2013 alongside the Bayonet, Flip Knife, Gut Knife, and Karambit, and it carried over to CS2 with an updated model. More than a decade later it is still one of the most wanted knives in the game.
This page covers the standard M9 Bayonet, usually called the vanilla. It has no paint finish, just the bare knife. That makes it the reference point for the whole M9 Bayonet range, and one of the more liquid knives on the market, with listings on most marketplaces at any time.
If you are looking for a painted version such as a Doppler, Fade, or Marble Fade, each finish has its own page. The most popular are linked below, and you can browse all M9 Bayonet skins in one place.
Design
The M9 Bayonet is a large military knife, originally built to mount on a rifle. In CS2 it has a long clip-point blade, a serrated section along the spine, a crossguard with a muzzle ring, and a dark textured grip. It is noticeably bigger on screen than the standard Bayonet, which is a large part of its appeal.
The vanilla version shows that shape with nothing added: a grey steel blade and a black handle. There is no pattern to check, so every vanilla M9 Bayonet looks the same.
How to Get an M9 Bayonet
There are three ways to get an M9 Bayonet in CS2.
- Buy it from a marketplace. This is the route most players take, because it is the only one with a certain result. The offers at the top of this page show every marketplace with a listing.
- Open a case. The M9 Bayonet is a rare special item in the original run of CS:GO weapon cases, including the CS:GO Weapon Case series, the eSports cases, and the Operation Bravo, Phoenix, and Vanguard cases. It also appears in the Revolver Case and in the Chroma and Gamma cases, which carry their own sets of finishes. The cases linked on this page are the ones that can drop the vanilla. Knife drops are rare, at around 0.26% per case.
- Trade up to it. Since October 2025, a trade-up contract using Covert skins can produce a knife from an eligible case.
M9 Bayonet Finishes
The vanilla is one of many M9 Bayonet skins. Finishes came in three waves, and each has its own page with live prices.
- Original finishes. The first set, from the early cases. Includes the M9 Bayonet | Fade, Slaughter, Case Hardened, and Crimson Web.
- Chroma finishes. Added with the Chroma cases. Includes the M9 Bayonet | Doppler, with its Ruby, Sapphire, and Black Pearl phases, plus the Marble Fade and Tiger Tooth.
- Gamma finishes. Added with the Gamma cases. Includes the Gamma Doppler, with its Emerald phase, the Lore, Autotronic, and Black Laminate.
Vanilla, Wear, and StatTrak™
The vanilla M9 Bayonet is not sold by wear condition. There is no Factory New or Battle-Scarred version to choose between, which makes it simpler to buy than a painted knife: one item, one market price.
It comes in two versions, standard and StatTrak™. The StatTrak™ version counts your kills with the knife and is listed separately, so you can compare the two using the toggle above. There is no Souvenir M9 Bayonet.
What Drives the Price of an M9 Bayonet
- The knife itself. The M9 Bayonet is one of the most popular knife models in CS2, so every version, the vanilla included, sits in the upper part of the knife market.
- Finish. Across the range, the finish matters more than anything else. Doppler gem phases, Fades, and rare Case Hardened patterns sit well above the vanilla, while finishes such as Safari Mesh or Boreal Forest often sit below it.
- StatTrak™. The StatTrak™ vanilla is scarcer than the standard one and priced separately.
- Case supply. Most of the cases that drop it are no longer in the active drop pool, so few new knives enter the market.
- The wider knife market. Because the vanilla has no float or pattern, its price moves with demand for knives in general. That makes its price history a useful read on the M9 Bayonet range as a whole.
The vanilla trades often, so prices between marketplaces stay closer together than they do on rare skins. It is still worth comparing the offers above, and setting a price alert if you are waiting for a level.
Similar Knives
- Bayonet. The closest relative. A slimmer, plainer blade from the same original set, and usually a cheaper way into the style.
- Karambit. The other headline knife from the original five, with a curved blade and its own animations.
- Butterfly Knife. A later release that competes with the M9 Bayonet for the top of the knife market.
- Flip Knife and Gut Knife. The lower-cost knives from the same cases.
