Butterfly Knife | Ultraviolet

Origin Story

The Butterfly Knife | Ultraviolet, released on March 16, 2017, with the "Take a trip to the Canals" update, is a classic, minimalist black and purple knife. It features individual parts spray-painted in solid colors, creating a clean aesthetic. This finish is considered a mid to high-tier option for players who appreciate dark, low-key knives and seek a straightforward play-skin. Its elegant design and brutal intent, as described by its flavor text, make it a respected choice for personal taste and loadout cohesion, especially within purple and black themed inventories.

Drop Chance

Butterfly Knife | Ultraviolet is a knife-tier skin, so standard Valve rarity odds don't apply. Knives drop at a combined rate of approximately 0.26% from supported cases before accounting for which knife type and finish you get. Valve doesn't publish individual knife or phase probabilities.

Skin Condition

Float range 0.06 to 0.8. Exteriors: Factory New, Minimal Wear, Field-Tested, Well-Worn, Battle-Scarred. StatTrak is available in FN, MW, FT, WW, BS.

• Factory New ($1,815.67): The black base and purple accents are fully crisp with no visible wear, presenting a pristine appearance.
• Minimal Wear ($1,091.05): Paint is almost fully intact, with strong black and purple contrast, showing only minor edge wear or tiny scratches mainly along the blade edge and possibly the pivot area.
• Field-Tested ($900.00): More noticeable edge wear appears on the blade tip, cutting edge, and along the back of the blade, with some dulling of the black and purple where bare metal starts to show through.
• Well-Worn ($910.95): Chipping and scratching are pronounced along blade edges and high-contact corners, with more of the underlying metal tone becoming visible, giving a more rugged, used look.
• Battle-Scarred ($777.00): The blade can appear heavily worn, with substantial gray showing through the black paint and more subdued purple on the handle, making the knife read as a distressed black with purple accents.

Sticker Compatibility

The Butterfly Knife | Ultraviolet does not have sticker slots, so sticker compatibility refers to how well it pairs with other weapon skins and agents in a themed inventory. Its black and purple color scheme complements purple, violet, or pink stickers, as well as minimalist black, gray, or white designs on other weapons. Gold or yellow holo stickers can also provide a contrasting accent within an Ultraviolet-themed loadout.
