★ Ursus Knife
Straightforward by design, the ★ Ursus Knife is a Covert tanto-style survival knife featuring a faceted blade, full tang construction, and an impact pommel. Valve emphasizes its no-nonsense reliability with no moving parts, just a blade ready for immediate use. It is obtainable from the Horizon Case, Danger Zone Case, Prisma Case, and Prisma 2 Case, and StatTrak versions are available. The faceted blade geometry interacts distinctively with light reflections, making the surface texture noticeable across different in-game environments.
