If you filter knives on C5GAME or the Steam Community Market and pick a Breakout-era profile, Ultraviolet shows up under the same finish name you know from Chroma solid colors—community tag Ultraviolet, internal id so_purple. The promo art sits on the Survival Knife: black base, purple panels, part-by-part paint. It reads restrained until you flip it in inspect; then the contrast line along the blade and guard is hard to ignore.

Parts of this weapon have been spray-painted solid colors in a purple and black color scheme.

Shopping verdict

Worth chasing if you want a cold, two-tone knife without busy patterns—especially on slim profiles like the Survival Knife where purple blocks stay readable at mid float. Skip or wait if you need factory-fresh purple sheets; solids punish high float on edges and spine, and listing wear alone lies.

Before you pay: match case → knife model → finish name. Ultraviolet in Fever Case rolls onto Breakout-related knife types in that drop table—not every knife line. Confirm in-game inspect and the exact listing on C5GAME or Steam; same finish name on a different silhouette is an expensive misclick.

Release

March 31, 2025, with the Spring Forward wave—same date patch notes and wikis use if you are timing a recolor or filling a gap in a loadout.

Designer

Valve in-house; part of the Chroma solid-color family stretched onto newer knife silhouettes.

Case

Fever Case—Breakout-related knives in that pool can drop Chroma-style finishes including Ultraviolet. Double-check the case label against the knife you are targeting before unboxing or buying a specific key route.

Finish facts

• Rarity: Rare
• Type: Solid color
• Float: 0.06–0.80 (Factory New through well-used band most traders care about)

On solids, wear usually shows on edges, guard, and spine—purple dulls, black eats more real estate as float climbs. Lower floats keep purple faces cleaner. On the Survival Knife, grip-to-blade proportions make the color break obvious in inspect; overall vibe is cool and minimal, not loud graffiti.

What to look at in inspect

The “pattern” here is which parts got purple vs black base—you only see that by rotating in 3D. From ~0.06 toward 0.80, watch guard, spine, and blade junction for graying and base peek—not the float number in isolation.

Cross-shop the same model on C5GAME and Steam: align wear tier and inspect screenshots. Ultraviolet on the wrong knife type still says Ultraviolet in the name.

Expert mutterings

Ultraviolet is the finish people buy when they are tired of neon fades but still want a knife that reads in third person. I treat it like buying paint on a car: the flat panels matter, but the trim tells the true float story. Fever Case hype will spike supply; the patient buyers win on guard wear comparisons, not on who refreshed market sort first. If your OCD wants one uniform purple face, budget for the lower half of the float band or accept that mid-tier solids are a mood, not a flex.

Bottom line: Strong pick for minimalist purple/black loadouts on supported Breakout knives—verify case, model, and inspect before checkout on C5GAME or Steam.
