Ursus Knife | Ultraviolet

Origin Story

The Ursus Knife | Ultraviolet, released on March 14, 2019, with the Seeing the Light update, features a design characterized by its elegant form and brutal intent. Its visual identity is defined by individual parts spray-painted solid colors in a black and purple scheme. This finish results in large, uniform color blocks, presenting a subtle and understated appearance. The knife is a straightforward, dark-themed option for players who prefer minimal color over flashy patterns.

Drop Chance

Ursus 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 ($442.44): The blade and handle appear clean and uniform, with deep black and solid purple panels and minimal visible scratches or edge wear.
• Minimal Wear ($166.75): The finish remains very close to Factory New, with strong color and only minor edge wear, usually at the tip, blade edge, or corners of the handle, making it a value pick.
• Field-Tested ($126.50): Noticeable wear appears on blade edges and the tip, with more exposed base material and some small patches of wear forming along the spine or high-contact areas.
• Well-Worn ($121.15): Significant edge wear is present, with larger patches of exposed base material along the blade edge, tip, and around the spine, and purple areas may look more faded and interrupted by scratches.
• Battle-Scarred ($118.88): Heavy wear covers large sections of the blade and some handle surfaces, with substantial base metal showing, making the black and purple paint appear dull, patchy, and heavily scratched.

Sticker Compatibility

The Ursus Knife | Ultraviolet does not support stickers, as knives cannot be stickered in CS2. However, its black and purple color scheme pairs well with black or purple-themed stickers on other weapons in a coordinated loadout. Community discussions often highlight matching Ultraviolet finishes with purple-hued holographic stickers or dark-themed team stickers on complementary firearms.
