★ Butterfly Knife | Case Hardened (Field-Tested)
The ★ Butterfly Knife | Case Hardened (Field-Tested, FT) is a Covert-rarity knife finish carrying a blue, gold, and steel case-hardened patina. Field-Tested is the middle grade of the finish's full range, keeping the patina legible at a lower price than the top two grades.
Design
The patina comes from color case-hardening the steel with wood charcoal under high heat, leaving an uneven mix of blue, gold, and steel rather than any painted artwork. It's paired with the line "A little color never hurt anyone." The paint seed on a given copy decides exactly how that color splits, and seeds weighted heavily toward blue — the "blue gem" copies — are what collectors chase hardest.
★ Butterfly Knife | Case Hardened (Field-Tested) Float and Wear
With float running the entire 0.00 to 1.00 span, this finish covers all five grades, and Field-Tested sits in the middle of that spread. Some added surface texture and light scuffing shows up at this level, but the case-hardened coloring stays clearly readable since it doesn't fade or shift the way a painted skin's saturation might. Field-Tested covers about 0.15–0.38 on the float scale.
Butterfly Knife | Case Hardened Rarity
This finish carries Covert ★ rarity, the rare special ("knife") classification set apart from ordinary weapon tiers. Any knife pull from a case counts as a genuinely uncommon outcome.
Butterfly Knife | Case Hardened Case and Collection
It's a drop from the Operation Breakout Weapon Case, where the odds of pulling a knife land at roughly 0.26%.
Butterfly Knife | Case Hardened Blue Gem Patterns
No other angle on this finish matters more than the paint seed — Case Hardened is the blue-gem finish, and the seed alone decides whether a copy leans blue or leans gold-and-steel. Copies get sorted into tiers by that blue coverage, with pattern #182 standing as the legendary top seed at roughly 94% blue, the market's benchmark and the most sought-after Butterfly blue gem there is; a small Tier-1 cluster of other heavily blue seeds sits just under it, then a long tail of lesser patterns fills out the rest. Since the seed never changes once a copy exists, a strong blue gem outguns a plain gold-and-steel copy at any wear.
StatTrak & Souvenir
A StatTrak edition of this knife exists too, adding a kill counter that becomes permanent once it starts tracking and travels with the item through every trade. Souvenir versions were never made for knives, since Major-tournament souvenir packages don't include them.
Butterfly Knife | Case Hardened Price
Field-Tested lands in the middle of the five-grade ladder, cheaper than Factory New (FN) and Minimal Wear (MW) but above Well-Worn (WW) and Battle-Scarred (BS). Case Hardened's mid-tier standing among this knife's finishes holds regardless of grade, and a strong blue seed can make a Field-Tested copy worth more than a plain Factory New. It's available to buy on Skin.Land with instant delivery and no hidden fees.
FAQ
Is Field-Tested a good middle ground for Case Hardened?
Yes — it costs less than the top two grades while keeping the case-hardened patina fully legible, since the coloring doesn't fade with wear the way a painted finish can. The main trade-off is a bit more surface texture and light scuffing, which matters far less than the paint seed does.
What is the best Butterfly Knife Case Hardened blue gem seed?
The seed matters more than the wear grade here. Pattern #182 is the top-regarded blue gem at roughly 94% blue, the market's benchmark and the most sought-after Butterfly Case Hardened seed. A small Tier-1 group of other heavily blue seeds ranks close behind, ahead of a long tail of more ordinary patterns — and a Field-Tested copy carrying a great seed still holds that value.
What are the best gloves for the Butterfly Knife | Case Hardened?
Blue-toned gloves play well against a blue-heavy seed, while gold or bronze-accented pairs pick up the warmer patches of the patina. It's a flexible finish for loadout matching since the blade already mixes cool and warm tones. For the best Butterfly Knife Case Hardened glove combo, echo those tones rather than fighting them.
