★ Butterfly Knife | Stained (Factory New)

The ★ Butterfly Knife | Stained (Factory New, FN) is a Covert ★ knife finish built from a forced patina, with lemon and mustard dripped onto the blade's surface. Factory New is the cleanest grade it comes in, showing that patina texture at its most vivid.

Design

Stained gets its look from a forced patina process — lemon and mustard dripped onto the blade to etch a mottled, streaked surface rather than a painted graphic. It carries the flavor line "If you think it's messy now, wait until you see it under a blacklight."

★ Butterfly Knife | Stained (Factory New) Float and Wear

Stained runs the full 0.00–1.00 float range, and Factory New sits at the very bottom of it. At this grade the streaked patina reads sharpest, with the least surface noise layered on top of the etched texture. On the float scale, Factory New spans 0.00–0.07.

Butterfly Knife | Stained Rarity

Rarity: Covert ★ — this is the gold-tier rare special ("knife") slot, not a standard Covert weapon skin, so pulling it at all is the scarce part regardless of wear.

Butterfly Knife | Stained Case and Collection

This finish isn't tied to any single collection; it comes from the Operation Breakout Weapon Case specifically. The rare-special ("knife") tier as a whole lands around 0.26% per case opening, which is why most buyers pick theirs up on the market instead.

Butterfly Knife | Stained Patterns

There's no rare "blue gem" seed to chase on Stained, but the patina texture itself does vary from copy to copy based on the paint seed — some copies etch cleaner and more evenly than others. Collectors do pay attention to seed here, even though there's no single grail pattern the way there is on some other finishes.

StatTrak & Souvenir

A StatTrak™ version of this knife exists and permanently tracks confirmed kills through any trade or sale. There's no Souvenir version at all — knives are never included in Major-tournament souvenir packages, regardless of case or finish.

Butterfly Knife | Stained Price

Factory New sits at the top of Stained's own price ladder, though the finish overall is the most accessible entry point among this knife's finishes — it's still a genuinely premium item, since no Butterfly Knife finish is cheap. It's available to buy on Skin.Land with instant delivery and no hidden fees.

FAQ

What case is the Butterfly Knife Stained in?

It comes specifically from the Operation Breakout Weapon Case rather than a wider spread of boxes. With the knife tier landing around 0.26% per case, most buyers find it faster to just buy the finish directly.

Does the seed matter on the Stained finish?

There's no rare "blue gem" pattern to chase, but the patina texture does vary by seed — some copies etch more evenly than others, and collectors do seek out the cleaner-looking seeds. It's not a case of every copy being identical.

What are the best gloves for the Butterfly Knife | Stained?

Since the patina leans into muted yellow, olive, and gray streaking, gloves in tan, olive drab, or worn-leather tones play well off that etched texture. Bright, glossy gloves tend to clash with the rough patina look instead of complementing it. For the best Butterfly Knife Stained glove combo, lean into those earthy, weathered tones rather than a flashy pair.
