League of LegendsSurvival Knife Doppler phases
The Doppler has 7 versions, each with its own paint index: Phase 1, Phase 2, Phase 3 and Phase 4, plus Ruby, Sapphire and Black Pearl. Right now Phase 2 is the priciest numbered phase in Factory New and Phase 1 the cheapest. Valve doesn't publish phase odds, so the phase is only visible on the knife itself or on a phase-tagged listing.

| Phase 1 | 418 | $175.00 | $262.15 | 27 |

Rare Survival Knife Doppler patterns
Within a phase, the pattern seed decides how much of the blade shows the phase's best color. Collectors pay extra for the strongest examples: mostly-pink Phase 2s, mostly-blue Phase 4s and dark Phase 1s.
| Phase | Premium patterns | What collectors look for |
|---|---|---|
| Phase 1 | Dark seeds | A near-black playside that resembles a Black Pearl |
| Phase 2 | Max Pink seeds | Pink and purple across the blade, with little black |
| Phase 3 | Green and blue seeds | A strong green tone across the blade |
| Phase 4 | Max Blue seeds | Mostly blue, close to a Sapphire look |
Survival Knife Doppler float and wear
The ★ Survival Knife | Doppler's float runs from 0.00 to 0.08, which covers Factory New and Minimal Wear. Within such a narrow range the wear difference is barely visible, so phase and pattern matter far more than float.

About the Survival Knife Doppler
The ★ Survival Knife | Doppler was added in March 2025.
“This multi-purpose tactical knife features a serrated edge for ripping through coarse material like bone or fiber, plus a sharp gutting hook. The composite material handle is bolted to the blade with hex nuts. It has been painted with black and silver metallic paints using a marbleizing medium, then candy coated.”
