Ursus Knife | Stained

Origin Story

The Ursus Knife | Stained was released on August 3, 2018, as part of the A New Horizon update, which introduced the Gamma and Gamma 2 Cases. This knife finish features a forced patina effect, achieved by dripping lemon and mustard onto the surface, resulting in a worn, stained steel appearance rather than bright metal. While not a high-status collector's item, the Stained finish offers a utilitarian aesthetic, often described as a "dirty" or "used" look. It serves as an accessible entry point for players seeking an Ursus knife model without the premium cost of more elaborate finishes.

Drop Chance

Ursus Knife | Stained 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 to 1. Exteriors: Factory New, Minimal Wear, Field-Tested, Well-Worn, Battle-Scarred. StatTrak is available in FN, MW, FT, WW, BS.

• Factory New ($260.12): The blade appears relatively clean and bright for a Stained finish, with the patina spots showing high contrast and sharp edges, retaining a distinct metallic sheen.
• Minimal Wear ($134.98): The blade is still very close to Factory New, with well-defined patina spots and streaks, though with a slight reduction in shine and a marginally more uniform discoloration.
• Field-Tested ($115.28): The blade looks noticeably duller, with the patina coverage appearing more continuous and less contrast between the clean metal and stained areas, conveying a more heavily used aesthetic.
• Well-Worn ($118.35): The blade is darker and more uniformly tarnished, with very subdued metal reflections, and the stains begin to merge into a mostly brownish-grey film, especially on larger surfaces.
• Battle-Scarred ($114.41): The blade becomes very dark and heavily tarnished, with the least visible sheen as the patina covers nearly everything, making the knife appear almost uniformly dirty or brownish-grey at extreme floats.

Model

Stained uses the legacy Ursus Knife model, introduced with A New Horizon on August 3, 2018. The inspect animation and third-person appearance match the original CS:GO version.

Visual Theme

Patina: It has been given a forced patina using lemon and mustard dripped onto the surface. The dominant colors are muted silver and steel, with grey-brown, yellowish, and darker patches from the patina. The blade's blotchy, stained pattern is the most identifiable element in first-person view. Stained knives are often compared to dirty, rusty, or used metal.
