★ Butterfly Knife | Case Hardened (Factory New)

The ★ Butterfly Knife | 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 sits at the clean, low-float end of the full 0.00–1.00 range, making it the pick for showing off the strongest blue coverage a given paint seed has to offer.

Design

The blade's coloring comes from being color case-hardened through wood charcoal applied at high heat, leaving an irregular blue, gold, and steel patina rather than any painted graphic. It carries the line "A little color never hurt anyone." The paint seed is what decides how the blue, gold, and steel land on a given copy, and the seeds that skew heavily blue — the "blue gem" copies — sell for far more than the rest.

★ Butterfly Knife | Case Hardened (Factory New) Float and Wear

Case Hardened spans the full float range from 0.00 to 1.00, so all five grades exist, and Factory New sits right at the clean end of that scale. At this grade the case-hardened zones read at their sharpest, with crisp separation between the blue, gold, and steel patches and none of the roughness that starts showing up on lower grades. Factory New occupies the 0.00–0.07 float band.

Butterfly Knife | Case Hardened Rarity

This is a Covert ★ item — the gold-tier rare special drop that sits apart from the ordinary weapon rarity ladder. Pulling any knife from a case is a long shot to begin with, and this finish is no exception.

Butterfly Knife | Case Hardened Case and Collection

This finish comes from the Operation Breakout Weapon Case, and the rare-special pull rate for landing a knife out of it sits at roughly 0.26%.

Butterfly Knife | Case Hardened Blue Gem Patterns

Case Hardened is the blue-gem finish of the whole knife line, and the paint seed is what decides everything — how much blue lands on the blade against the gold and steel, with copies ranked into tiers purely by that coverage. Pattern #182 is the legendary seed here, roughly 94% blue across the blade, the most valuable and sought-after Butterfly blue gem and the market's benchmark; a small Tier-1 group of other heavily blue seeds sits near it, followed by a long tail of lesser patterns. That seed is locked in for the life of the copy and never shifts with wear, so a heavy blue gem outguns an ordinary gold-and-steel copy at any 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 and sale. There's no Souvenir edition, since knives are never included in Major-tournament souvenir packages.

Butterfly Knife | Case Hardened Price

Factory New sits above the four lower grades on this finish's own ladder, and Case Hardened as a whole ranks mid-tier among this knife's finishes. It's a genuinely priced item within the lineup rather than an entry point, and a standout blue seed can push any grade well past a plain one. It's available to buy on Skin.Land with instant delivery and no hidden fees.

FAQ

What case is the Butterfly Knife Case Hardened in?

It comes from the Operation Breakout Weapon Case, and the odds of pulling any knife out of it sit at roughly 0.26%. That rate applies to the knife slot as a whole, not to any single finish or paint seed within it.

What is the best Butterfly Knife Case Hardened blue gem seed?

Pattern #182 is the legendary top seed — roughly 94% blue across the blade, the most valuable and sought-after Butterfly Case Hardened blue gem and the market's benchmark. A small Tier-1 group of other heavily blue seeds sits close behind it, ahead of a long tail of lesser patterns. The seed is fixed per copy for good, so it never changes as the knife wears.

Is the mid-tier pricing on Case Hardened still worth it?

Yes — mid-tier here is relative to this knife's own pricier finishes, not a discount item. What separates copies most isn't grade so much as paint seed, since a heavily blue seed can outvalue a plain gold-and-steel copy at any wear level, Factory New included.
