★ M9 Bayonet | Case Hardened (Factory New)

The ★ M9 Bayonet | Case Hardened (Factory New) is a Covert-rarity knife finish carrying a blue, gold, and steel patina from a color case-hardening process. Factory New covers the 0.00–0.07 band at the clean end of the full 0.00–1.00 range, and it's the grade blue-gem hunters usually chase when they want the clearest read on a paint seed.

Design

The blade's coloring comes from being color case-hardened with wood charcoal at high temperature, which leaves an irregular blue, gold, and steel patina rather than any printed graphic. It carries the line "A little color never hurt anyone." That patina isn't random — the paint seed decides exactly how much blue lands where, and the heaviest blue seeds trade at levels the ordinary gold-and-steel copies never touch.

★ M9 Bayonet | Case Hardened (Factory New) Float and Wear

Case Hardened spans the entire float range from 0.00 to 1.00, so every one of the five grades exists, with Factory New anchoring the top. At this float the case-hardened zones show at their sharpest, with clean separation between blue, gold, and steel and none of the surface texture that starts creeping in further down the wear ladder. Factory New occupies the 0.00–0.07 float band.

M9 Bayonet | Case Hardened Rarity

Rarity here is Covert ★, the gold-tier rare special classification knives carry, sitting apart from the ordinary weapon rarity scale entirely. Landing any knife from a case is a long shot regardless of finish.

M9 Bayonet | Case Hardened Case and Collection

Case Hardened is one of the original knife finishes, so instead of one source it turns up across a wide range of cases, including the CS:GO Weapon Case and the Operation Phoenix Weapon Case among many others over the years. Whichever case produces it, the rare-special pull rate sits at roughly 0.26 percent.

M9 Bayonet | Case Hardened Blue Gem Patterns

Case Hardened is the blue-gem finish of the M9 Bayonet lineup, and the paint seed is the whole story — it fixes how much blue versus gold and steel covers the blade, and copies get ranked into tiers purely on that coverage. Pattern #601 is the legendary standout, a roughly 92 percent blue blade regarded as the top M9 blue gem and the market's benchmark, followed by a group of other high-tier seeds such as #417, and then a long tail of more ordinary blue patterns. That seed locks in the moment the knife is minted and never shifts with wear afterward, so a heavy blue gem in Factory New commands far more than a plain gold-and-steel copy at the same grade.

StatTrak & Souvenir

A StatTrak version of this knife exists alongside the regular one, adding a permanent confirmed-kill counter that carries through every trade or sale. There's no Souvenir edition — knives are never distributed through Major-tournament souvenir packages, no matter which case or seed produced them.

M9 Bayonet | Case Hardened Price

Factory New sits at the very top of this finish's price ladder, and Case Hardened as a whole already ranks as one of this knife's grail-tier finishes — among the most expensive this M9 offers. A strong blue seed pushes the price even higher, so Factory New here is squarely a top-shelf pick rather than an entry point. It's available to buy on Skin.Land with instant delivery and no hidden fees.

FAQ

What case is the M9 Bayonet Case Hardened in?

It's one of the original knife finishes and drops from a wide range of cases rather than a single one, including the CS:GO Weapon Case and the Operation Phoenix Weapon Case. No matter which case produces the knife, the rare-special pull rate lands at roughly 0.26 percent.

What is the best M9 Bayonet Case Hardened blue gem seed?

Pattern #601 holds that title — a roughly 92 percent blue blade widely treated as the top M9 blue gem and the market's benchmark. A group of other high-tier seeds, including #417, ranks close behind it, ahead of a long tail of lesser blue patterns. The seed is fixed for the copy's entire life, so it never changes with wear.

Is Factory New worth the premium over lower grades on this finish?

If a sharp, high-contrast read on the paint seed matters to you, yes — Factory New shows the blue, gold, and steel split at its clearest. That said, the seed itself (not the wear grade) drives most of the value here, so a great seed on a lower grade can still outprice an ordinary Factory New copy.
