The M9 Bayonet is one of the largest and most recognizable knives in CS2. It has been in the game since 2013 and has long been a status piece: a big army-style blade, the signature stab inspect animation, and a huge price range — from plain camo finishes at around $290 to Doppler gems that sell for several thousand dollars. There are no genuinely cheap options here, so the whole decision comes down to which finish you take and in what condition: for most players the Marble Fade at around $790 is the sweet spot, with a fixed pattern, a stable price and a bright look with no float lottery. This guide covers the best M9 skins in 2026 forevery budget: how each one looks, which loadouts it fits, where to get it and how well it holds its value.
M9 Bayonet | Marble Fade (best all-round)
The M9 Bayonet | Marble Fade is the M9 most players should buy. The red-blue-gold marbling is unique to every knife, and the most prized is the "Fire and Ice" layout, where red and blue meet on the front of the blade. The M9’s large blade shows the pattern across its full width, so the knife stands out in colorful loadouts and pairs easily with red or blue gloves.
This finish came to the M9 with the Chroma cases in 2015 and only exists in Factory New and Minimal Wear, so the blade always looks clean and you can ignore the float. As an investment it is one of the steadiest knives around: Covert rarity, even demand and good liquidity keep the price stable, while clean "Fire and Ice" pieces appreciate faster than the rest. Expect around $790.
M9 Bayonet | Doppler and gems
The top of the model is the Doppler family, and inside it the gems — the rarest and most expensive variants. Ordinary phases start at around $930 and Gamma Doppler from about $1290, but the real hunt is for the gems: Sapphire (around $4860), Emerald (around $7630), Ruby (around $8180, buy here) and the very rare Black Pearl (around $9020). A deep blue, green or red stone turns a loadout into a showcase on its own.
Doppler came to the M9 with those same Chroma cases in 2015 and, like every gradient, only exists in fresh conditions. A gem is a safe but illiquid buy: the price depends almost entirely on how cleanly the color shows, so these knives are chosen one specific piece at a time, and the gap between "decent" and "excellent" can be enormous.
M9 Bayonet | Fade
The M9 Bayonet | Fade is the flashiest of the classic finishes: a pink-to-yellow gradient graded by fade percentage, and the higher it is, the more the knife costs. The M9’s big blade shows the whole color transition, so the Fade is often the centerpiece of bright, high-contrast loadouts.
It is one of the oldest finishes in the game, from the original 2013 weapon cases, and comes only in Factory New and Minimal Wear, so you will never see wear on the blade. A reliable long-term pick, with full-fade pieces behaving like an appreciating asset. Price is around $990.
M9 Bayonet | Tiger Tooth
The Tiger Tooth is for people who don’t want to inspect anything: a smooth gold-and-black gradient with no pattern and virtually no float influence. On the M9 the gold reads large and expensive, and it sits well with warm, brass-toned loadouts.
Like the Marble Fade, the Tiger Tooth came to the M9 with the Chroma cases in 2015 and only exists in Factory New and Minimal Wear. Pieces are nearly identical to one another, which makes it one of the most liquid expensive M9s: easy to buy, low risk, and dependable at holding its value. Expect around $730.
M9 Bayonet | Slaughter
The M9 Bayonet | Slaughter is metallic-red marbling, unique on every knife; heart-shaped layouts and clean red command the highest prices. The rich red drops straight into aggressive red loadouts and skips the overloaded web look of the Crimson Web.
This is another finish from the 2013 weapon cases. It runs up to Field-Tested, but it hides wear well, so mid conditions still look good. Don’t expect strong growth — it is a steady mid-tier with stable demand and a small premium for a good layout. Around $650.
M9 Bayonet | Autotronic
The Autotronic is a restrained premium: a dark blue-green chrome that doesn’t shout. It fits cold, muted loadouts in blues and blacks rather than bright, busy ones.
This is a later finish: it came to the M9 with the Gamma cases in 2016 and exists in every condition, from Factory New to Battle-Scarred. At around $620 it is one of the cheapest ways into the "designer" tier; demand is steady, but people buy the Autotronic mainly for the look.
M9 Bayonet | Case Hardened
The M9 Bayonet | Case Hardened is the M9 for pattern hunters. It is a blue-gold-steel finish where the price is set not by wear but by the pattern index: ordinary pieces go into muted blue-steel loadouts, while a blade with a large blue patch (the "blue gem") is a genuine trophy.
An old finish, from the 2013 weapon cases, available in every condition. It starts at around $470, but blue-heavy pieces cost many times more and rank among the strongest knife investments in the game — though a good one takes patience to find. The logic is simple: buy an ordinary one for the look, or hunt a pattern for the long term.
M9 Bayonet | Crimson Web
The M9 Bayonet | Crimson Web is the second pattern skin here: red-and-black webs arranged differently on every knife, and several webs near the center of the blade lift the price sharply. The dark-red look is the backbone of horror and red loadouts.
One of the most legendary finishes in the game, again from the 2013 weapon cases. Wear is barely visible on the dark coating, so even cheap conditions look fine. Entry pieces start at around $450, while a knife with a full web is both a display piece and a solid investment that appreciates over time.
M9 Bayonet | Lore (best value)
The M9 Bayonet | Lore is the best look-for-the-money pick. The ornate gold filigree over a dark blade looks far more expensive than it is, and the busy artwork hides wear well, so even cheap pieces look rich. The gold begs to go into "luxury" loadouts.
Like the Autotronic, the Lore came to the M9 with the Gamma cases in 2016 and is available in every condition. At around $380 it is the most expressive look for the money among M9s; demand is consistently high, though as a later finish it is more of a pretty buy than a time-tested investment.
M9 Bayonet | Boreal Forest (cheapest entry)
The cheapest way to own an M9 is the plain camos. The cheapest is the Forest DDPAT, from $290, with the Boreal Forest just above it at around $300. The green forest camo fits military and "green" loadouts well.
Both camos are from the 2013 weapon cases. They make no real impression, but heavy wear is almost invisible on them, so even the cheapest pieces look tidy. As investments these are the weakest finishes in the lineup — people buy them for the model and the animation itself. If you want something non-camo, the next step up is the Ultraviolet at around $340.
Getting an M9 Bayonet: cases and crafting
The M9 Bayonet is a Covert-rarity knife, and there are two ways to get one. The first is to unbox it from knife cases: as one of the first knives in the game, from the 2013 Arms Deal update, the M9 drops as a rare special item with the same tiny odds as any other knife.
The second route is new: since autumn 2025 you can craft knives and gloves with a trade-up contract — you put in exactly 5 Covert skins of one type (all normal or all StatTrak, no mixing) and get a random gold item from the collections those skins belong to. Targeting a specific finish this way is hard, so for a particular look and condition the market is still simpler. And if your budget is under $150, the M9 is out of reach for now — take a look at the best knives under $150.
What affects an M9 Bayonet’s price
Four things drive the price of an M9 Bayonet, roughly in order of impact:
Finish type. Camos and solid colors hold the floor around $290, pattern and metallic finishes sit in the middle, and gradients and gems take the top.
Pattern and phase. On Case Hardened, Crimson Web, Slaughter and Doppler, two knives in the same condition can differ by thousands purely on layout or phase.
Float. It only matters where wear shows: on camos, Doppler, Fade and Marble Fade it has almost no effect on price.
StatTrak. On knives the counter adds only a small premium, and sometimes even narrows the pool of buyers, unlike "working" weapons (see affordable StatTrak skins).

Frequently Asked Questions
Is the M9 Bayonet worth it in CS2?
The M9 is valued for its size and classic status rather than rarity, so it comes down to how much that matters to you. Entry skins around $290 make it one of the most affordable classic knives, and popular finishes like the Marble Fade hold their price well and resell easily.
Which M9 skin is the best value?
The Marble Fade (around $790) is the middle ground between iconic looks and a stable price: the pattern is fixed and float-independent. If you want to stay under $400, the Lore gives you the most detail for the money.
Do float and pattern matter on the M9?
It depends on the skin. On camos, Doppler, Fade, Marble Fade and Tiger Tooth float barely matters. On Case Hardened, Crimson Web and Slaughter the layout can move the price by hundreds or thousands, so those are worth checking piece by piece.
What is the most expensive M9?
The Doppler gems are the most expensive, led by the Black Pearl (around $9020) and Ruby (around $8180); the exact price depends on how cleanly the color shows.
