★ Ursus Knife | Ultraviolet
Individual components of the ★ Ursus Knife | Ultraviolet have been spray-painted in solid black and purple tones, giving this Covert tanto knife a deliberate two-tone color scheme. It is obtainable from the Prisma Case and Prisma 2 Case. The float range spans 0.06 to 0.80, which removes both Factory New and Battle-Scarred from the attainable pool. Toward the higher end of the range, paint on the blade face and handle scales shows clear wear that breaks up the solid color blocking. StatTrak is available. The black-purple scheme reads sharply under most in-game lighting conditions.
Cheapest wear we have on this page. Pattern / float overpay is extra.
Prisma 2 Case: (case+key) ÷ drop chance. Average, not a promise.
Covert / missing collection peers: no contract estimate.
