★ Karambit | Case Hardened (Factory New)

The ★ Karambit | Case Hardened (Factory New) is a Covert-rarity knife finish with a blue, gold, and steel patina from a color case-hardening process. Factory New is the lowest-float, crispest grade available, and it's the pick for buyers hunting the strongest blue coverage on a given paint seed.

Design

The blade gets its look from being color case-hardened through wood charcoal applied at high heat, which leaves an irregular blue, gold, and steel patina rather than a painted pattern. It carries the line "A little color never hurt anyone." That patina isn't random noise — the paint seed decides how much blue lands where, and the most heavily blue "blue gem" copies trade far above ordinary ones.

★ Karambit | Case Hardened (Factory New) Float and Wear

Case Hardened runs the full float range from 0.00 up to 1.00, so it exists across all five grades, and Factory New sits at the very top of that scale. At this level the case-hardened patina reads at its clearest, with the blue, gold, and steel zones sharply defined and none of the surface roughness that creeps in on lower grades. Factory New occupies the 0.00–0.07 float band.

Karambit | Case Hardened Rarity

This is a Covert ★ item, the gold-tier rare special drop that stands apart from the usual weapon rarity ladder entirely. Any knife pull from a case is a rare event, and this finish is no exception.

Karambit | Case Hardened Case and Collection

Case Hardened is one of the original knife finishes, and rather than one source it's obtainable from 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 it comes from, the rare-special pull rate for a knife sits at roughly 0.26%.

Karambit | Case Hardened Blue Gem Patterns

Case Hardened is THE blue-gem finish of the whole knife lineup, and the paint seed is everything — it decides how much blue versus gold and steel ends up covering the playside, and copies get ranked into tiers purely by that blue coverage. The legendary pattern #387, a near-fully-blue face, is the top Karambit blue gem and the market's benchmark, with the most valuable copies having reached seven figures; it's joined by a small group of other Tier-1 seeds and then a long tail of lesser blue patterns. That seed is locked in for the life of the copy and never shifts with wear, so a heavy blue gem trades far above 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 trades and sales. There's no Souvenir edition — knives are never included in Major-tournament souvenir packages, no matter which case or seed produced them.

Karambit | Case Hardened Price

Factory New sits at the top of this finish's price ladder, above the four lower grades, and Case Hardened as a whole already ranks upper-mid among this karambit's finishes. It's a genuinely pricier pick within the knife's lineup rather than an entry point, though a strong 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 Karambit Case Hardened in?

It's one of the original knife finishes and shows up across a wide range of cases rather than a single one, including the CS:GO Weapon Case and the Operation Phoenix Weapon Case. Regardless of which case produces the knife, the rare-special pull rate lands at roughly 0.26%.

What is the best Karambit Case Hardened pattern / blue gem seed?

Pattern #387 is the legendary benchmark — a near-fully-blue face regarded as the top Karambit blue gem, with the most valuable copies having sold for seven figures. A small group of other Tier-1 seeds sits near it, followed by a long tail of lesser blue patterns. The seed is fixed per copy for good, so it never changes as the knife wears.

Is the most accessible Case Hardened grade still worth it?

Even the lower grades of this finish carry real value — this is upper-mid pricing within the knife's own lineup, not a cheap option. What changes most between grades is surface wear and how clearly the patina reads; the underlying paint seed and its blue-gold-steel split matter just as much to price as the wear grade does.
