Ursus Knife | Ultraviolet

The Ursus Knife | Ultraviolet is a modern CS2 knife skin known for its bold, high-contrast finish. As with many popular knife designs in the Counter-Strike ecosystem, Ultraviolet became a fan favorite thanks to its instantly recognizable color palette and clean, stylized pattern presentation on the blade and handle areas. In CS2, this knife continues to be a sought-after option for players who want a premium look with strong visual identity.

Classified as a Covert rarity, the Ursus Knife | Ultraviolet sits among the more desirable categories in the game’s skin economy. Covert skins are generally rarer than lower-tier options, meaning they’re less likely to appear during case openings compared to common and restricted items. While exact drop rates are not publicly guaranteed for every container, Covert items typically have a lower probability than more common tiers, making this knife a frequent target for collectors.

This skin comes in multiple wear levels, with the listed float range of 0.06 – 0.8. You can find it in: Factory New, Minimal Wear, Field-Tested, Well-Worn, and Battle-Scarred. Additionally, the StatTrak variant is available (Yes), allowing you to track confirmed kills in-game. A Souvenir version is not available, and there are no specific collections associated with this skin.

Visually, the Ultraviolet finish is designed to deliver a vivid purple-forward look with a striking, graphic style that stands out even in fast gameplay. The skin’s presentation is influenced by the game’s paint index: 98 and the CS2 knife model formatting, which together help define how the pattern and color placement appear across different wears.

For acquisition, the Ursus Knife | Ultraviolet can be found by opening cases where it’s included, specifically the Prisma 2 Case and Prisma Case. Collectors typically focus on these containers because they’re among the confirmed sources where this skin may appear, rather than through general trading alone.

In the community, the Ursus Knife line is widely respected for its compact, aggressive silhouette and strong inspect animations, and the Ultraviolet finish amplifies that appeal with a distinctive “premium purple” aesthetic. Many players gravitate toward this skin as both a personal main and a high-visibility upgrade, especially for those building a cohesive knife-and-gloves look in CS2.
