Beyond the four standard phases, three ultra-rare Doppler variants are far more valuable due to their unique coloring and extreme rarity. The unique Doppler patterns in these variants make them highly prized collectors’ items.

Knife Compatibility
Doppler skins are not available for all knife types in CS2. They were originally introduced with the Chroma Case and are limited to specific models, including:
Some newer knife models, like the Survival Knife and Skeleton Knife, currently lack Doppler finishes, though future updates may expand the availability. Players looking for affordable entry points into knife collecting might want to explore various budget options while saving for a Doppler.
How to Obtain Doppler Knives in CS2
Doppler knives can be acquired through opening cases, trading with other players, or purchasing from the Steam Community Market.
The most common cases containing Doppler knives include Chroma Cases and Gamma Cases, though availability may change as Valve updates the game.
Trading vs. Unboxing
While unboxing cases gives you the thrill of potentially finding a rare Doppler knife, trading is generally more cost-effective. The odds of unboxing a knife are approximately 0.25-0.30%, with even lower chances for specific Doppler phases. Consider using trusted third-party marketplaces like Tradeit where you can browse exact patterns and phases rather than gambling with cases.
