★ Butterfly Knife | Blue Steel (Field-Tested)

The ★ Butterfly Knife | Blue Steel (Field-Tested, FT) sits near the middle of this Covert ★ finish's full float range, where the cold-blued steel starts to pick up visible surface wear. It's a mid-grade look rather than a pristine or heavily battered one.

Design

Blue Steel's look comes entirely from cold-blued steel rather than paint, giving the blade a dark gray tone with a blue cast. At Field-Tested, that treatment is still clearly visible, just with a bit more texture showing than on the cleaner grades.

★ Butterfly Knife | Blue Steel (Field-Tested) Float and Wear

Because this finish uses the full 0.00–1.00 float scale, Field-Tested lands roughly in the middle of it, giving the blade a genuinely lived-in look without pushing all the way to the worn extreme reserved for Battle-Scarred (BS). The dark tone is visibly less uniform than at Factory New (FN). Field-Tested occupies the 0.15–0.38 float band.

Butterfly Knife | Blue Steel Rarity

Covert ★ marks this as the rare-special ("knife") pull, the gold-tier item type that ranks above standard weapon skins in the case it opens from. That classification is fixed regardless of which wear grade a copy ends up at.

Butterfly Knife | Blue Steel Case and Collection

This finish opens exclusively from the Operation Breakout Weapon Case, with no other source. The rare-special tier odds sit near 0.26% per case, so most Field-Tested copies are bought on the market rather than pulled directly.

Butterfly Knife | Blue Steel Patterns

Every copy of Blue Steel carries the identical cold-blued surface, since paint seed has no bearing on this finish's appearance. There's nothing pattern-wise to hunt for; float value is the only meaningful thing to compare before buying.

StatTrak & Souvenir

A StatTrak™ version tracks kills permanently on this knife, and that tally carries through trades and sales without resetting. Souvenir copies were never made for it, since knives don't appear in Major-tournament souvenir packages.

Butterfly Knife | Blue Steel Price

Field-Tested runs cheaper than both Factory New and Minimal Wear (MW) on the Blue Steel's ladder, though the finish overall still holds an upper-mid spot among this knife's lineup. It's available to buy on Skin.Land with instant delivery and no hidden fees.

FAQ

How worn does Field-Tested look on the Blue Steel?


It shows real, visible surface wear compared to the top two grades, since this finish uses the full 0.00–1.00 float range rather than a capped one. It's a genuine mid-point look — more texture than Minimal Wear, but nowhere near the roughest end Battle-Scarred can reach.


Does the cold-blued treatment vary between copies?


No — the dark gray-blue surface is a fixed design, identical across every copy regardless of paint seed. What changes at Field-Tested is purely the wear texture from the float value, not the underlying finish itself.


Is Field-Tested a reasonable middle ground for this knife?


Yes, if you want a lower price without going all the way to the most worn grade. It sits comfortably between the cleaner, pricier copies and the cheapest Battle-Scarred option, giving buyers a balance of cost and appearance.
