Flip Knife | Stained

Origin Story

The Flip Knife | Stained, released on August 14, 2013, with The Arms Deal update, is one of the original knife finishes available in CS2. Its blade features a distinctive forced patina, created by applying lemon and mustard to the surface, resulting in an irregular, tarnished appearance. This finish gives the knife a worn, realistic metal look, contrasting with more colorful patterns. It drops as a rare special item from several legacy weapon cases.

Drop Chance

Flip 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 ($272.91): The blade surface appears relatively clean and even, with clear stained patterning and less overall darkening; the patina looks more like intentional discoloration than heavy wear.
• Minimal Wear ($179.94): The patina pattern is still intact and readable, with only subtle additional dulling and micro-wear on high-contact areas like the cutting edge and near the tip.
• Field-Tested ($219.70): The blade metal becomes noticeably darker and more patchy, with patina stains blending into broader areas of discoloration, giving the knife a more heavily used appearance.
• Well-Worn ($191.06): Patina and discoloration are heavier and more uniform, giving the blade a very used, aged appearance; individual stain details are less distinct as the metal darkens overall.
• Battle-Scarred ($200.03): The blade is darkest and dullest here, with extensive patina coverage and rough-looking metal; the knife can appear almost industrial or corroded, which some players deliberately seek for thematic loadouts.
