Gamma Doppler is one of the go-to multicolor electroplated knife finishes. This write-up focuses on Phase 4: same finish name, different phase, different pattern real estate—thumbnail shopping is a trap.

Quick specs

• Item: Knife
• Finish: Gamma Doppler (Phase 4)
• Rarity: Mythical
• Style: Multicolor electroplating
• Float: 0.00–0.08 (essentially Factory New and Minimal Wear territory)

Valve’s brief: black and silver metallics blended like marble, tuned to hide how sharp the blade reads. The dark base keeps the silhouette serious; the electroplate throws depth in light. Up close it reads restrained but still dangerous. With no Battle-Scarred band, the face stays mostly intact—tip, edge, and spine are where float actually shows.

Release & origin

Dropped 15 June 2016 with Gamma Exposure and the Gamma Case. Official Valve art, same wave as the Gamma theme. Still a common upgrade path years later.

Where it trades

Unboxed from the Gamma Case; listings move on Steam and C5GAME. Hunting a specific phase? Match in-game inspect to the listing, not the store icon.

Wear & inspect checklist

The wear window is narrow. FN vs MW can be one subtle step apart—often visible only as edge highlight loss.

• Spin inspect: where Phase 4 green/blue sits on the blade matters more than average float.
• Collectors: lean FN when budget allows.
• Value picks: MW with clean edges and a clear marble read on the flat.

Shopping verdict

Worth shortlisting if you want a cold, detail-heavy melee skin with real market depth since 2016. Lock phase first, then haggle on float at the edges—not on paper float alone.

Editor’s notes

Phase 4 isn’t “better” than other phases; it’s different real estate. I always open inspect on C5GAME, screenshot the pattern, then compare Steam ask. Two MW listings can look like different skins depending on tip wear—don’t skip that step.
