★ Flip Knife | Case Hardened (Factory New)

The ★ Flip Knife | Case Hardened (Factory New) is a Covert-rarity knife finish with a blue, gold, and steel patina produced by color case-hardening. Factory New is the least-worn grade you can get, and it's the pick for buyers chasing the cleanest read on whatever blue coverage a given paint seed carries.

Design

This blade's coloring comes from color case-hardening it with wood charcoal at high heat, which leaves an irregular blue, gold, and steel patina rather than a painted graphic. It carries the flavor line "A little color never hurt anyone." That patina isn't uniform — the paint seed decides how the blue lands against the gold and steel, and the most heavily blue "blue gem" copies sell for far more than an ordinary one.

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

Case Hardened runs the complete float range on this knife, from 0.00 up to 1.00, so all five grades exist, with Factory New sitting at the very top. At this level the case-hardened coloring reads at its sharpest, with the blue, gold, and steel zones cleanly defined and none of the surface texture that starts creeping in on lower grades. In float terms, this grade runs 0.00–0.07.

Flip Knife | Case Hardened Rarity

This is a Covert ★ item, the gold-tier rare special drop that sits apart from the regular weapon rarity ladder entirely. Any knife pull from a case is a long shot by design, and this finish is no exception.

Flip Knife | Case Hardened Case and Collection

Case Hardened is one of the original knife finishes, so instead of one source it's obtainable from a wide range of cases, with the CS:GO Weapon Case and the Operation Phoenix Weapon Case among the more iconic of many. Whichever case it drops from, the rare-special pull rate for a knife holds at roughly 0.26%.

Flip Knife | Case Hardened Blue Gem Patterns

Case Hardened is the blue-gem finish of the whole lineup, and the paint seed decides everything — how much blue lands against gold and steel, with copies ranked into tiers purely on that coverage. The legendary seed for this knife is pattern #670, an almost fully blue face from base to tip with just a hint of yellow at the point, standing as the market's number one benchmark, and it's followed closely by #321 and a small Tier-1 group; only a handful of the 1,000 possible seeds qualify as blue gems at all. That seed is locked in for the life of the copy and never shifts with wear, so a heavy blue gem trades far above a plain 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 — knives are never included in Major-tournament souvenir packages, regardless of which case or seed produced them.

Flip Knife | Case Hardened Price

Factory New sits at the top of this finish's price ladder, above the four lower grades, and Case Hardened overall lands mid-tier among this knife's own finishes. A strong blue seed can still push any grade well past a plain one, so the seed matters as much here as the grade does. It's available to buy on Skin.Land with instant delivery and no hidden fees.

FAQ

What case is the Flip Knife Case Hardened in?

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

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

Pattern #670 is the legendary top seed — an almost fully blue face from base to tip with just a hint of yellow at the point, treated as the market's number one benchmark for this knife. Pattern #321 sits closely behind it, alongside a small Tier-1 group; only a handful of the 1,000 seeds qualify as blue gems at all. The seed never changes as the knife wears.

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

Yes — this finish sits mid-tier within the Flip Knife's own lineup, which still makes it a genuinely premium item, not a budget one. What separates copies most isn't the wear grade so much as the paint seed, since a strong blue seed can outvalue a plain one at any grade.
