★ Ursus Knife | Stained
The Ursus Knife | Stained draws its finish from a forced patina process, with lemon and mustard dripped onto the blade to produce irregular staining across the faceted tanto-style surface. This Covert knife comes from the Horizon Case and Danger Zone Case, and StatTrak versions exist. The float range covers the full 0 to 1 window, so low-float examples show subtle, concentrated stain patterns, while higher floats introduce additional surface wear that blends with the existing patina, deepening the discolored, organic texture across the blade.
Cheapest wear we have on this page. Pattern / float overpay is extra.
Danger Zone Case: (case+key) ÷ drop chance. Average, not a promise.
Covert / missing collection peers: no contract estimate.
