★ M9 Bayonet | Case Hardened (Battle-Scarred)

The ★ M9 Bayonet | Case Hardened (Battle-Scarred) is a Covert-rarity knife finish showing its blue, gold, and steel case-hardened patina at the most heavily worn grade. It's the most accessible way into this finish's pattern, trading surface polish for the lowest price on the ladder.

Design

The patina is produced by case-hardening the steel with wood charcoal at high temperature, leaving an irregular blend of blue, gold, and steel across the blade rather than a painted design. It comes with the line "A little color never hurt anyone." That blend's exact layout is set by the paint seed, and the rare seeds carrying heavy blue are prized well above the rest no matter the grade.

★ M9 Bayonet | Case Hardened (Battle-Scarred) Float and Wear

Case Hardened's float runs the complete 0.00 to 1.00 range, and Battle-Scarred sits at the bottom of that scale, showing the heaviest scuffing and surface roughness of any grade. Since the coloring comes from case-hardening rather than a coat of paint, the blue, gold, and steel pattern remains just as visible here as on a pristine copy — only the surface texture changes. Battle-Scarred occupies the 0.45–1.00 float band.

M9 Bayonet | Case Hardened Rarity

Rarity is Covert ★, the rare special ("knife") tier that stands apart from the standard weapon rarity grades. Every copy of this knife, worn or not, carries that same rare-special status.

M9 Bayonet | Case Hardened Case and Collection

This finish is one of the originals and has dropped from a long list of cases across the game's history, including the CS:GO Weapon Case and the Operation Phoenix Weapon Case among many others. No matter the source case, a knife pull lands at roughly 0.26 percent.

M9 Bayonet | Case Hardened Blue Gem Patterns

This is the finish that made "blue gem" a term collectors search for, and it all comes down to the paint seed: it fixes how much blue a copy shows against gold and steel, and every copy gets ranked into a tier on that basis alone. Pattern #601 tops the list at roughly 92 percent blue, standing as the market's M9 benchmark, followed by a group of other high-tier seeds such as #417 and then a long tail of more ordinary blue patterns. The seed never moves once it's set, so a Battle-Scarred copy carrying a great blue seed is judged on that seed, not on how scuffed the surface looks.

StatTrak & Souvenir

A StatTrak version of this knife also exists, adding a permanent kill counter that carries through any trade once it's activated. Souvenir editions were never produced for knives, since Major-tournament souvenir packages exclude them entirely.

FAQ

Is the Battle-Scarred Case Hardened worth it?

If the paint seed leans blue, absolutely — the case-hardened pattern doesn't fade with wear, so a "blue gem" Battle-Scarred copy still shows that prized coloring clearly. It's the cheapest way to own the finish, making it a solid pick for buyers prioritizing pattern over polish.

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

Pattern #601 holds that title — a roughly 92 percent blue blade regarded as the market's benchmark blue gem. A group of other high-tier seeds, including #417, trails it, ahead of a long tail of lesser blue patterns. Because the seed never changes with wear, that ranking applies exactly the same to a Battle-Scarred copy as to any other grade.

Does the M9 Bayonet Case Hardened have StatTrak at Battle-Scarred?

Yes, StatTrak is available across every grade of this finish, including Battle-Scarred, adding a permanent kill counter. There's no Souvenir version at any grade, since knives are never part of Major-tournament souvenir packages.
