Among CS knife finishes, Doppler is instantly readable: a black-and-silver marble base with a glossy “candy coat” electroplate on top. This guide zeroes in on Phase 3—catalog 420, internal name am_doppler_phase3, display knife | Doppler—knife class, Mythical, multicolor electroplating. Valve’s brief: marble look in black and silver metal paint, wrapped in that sugary sheen. The flavor line fits: looks can seriously mislead you.

Shopping conclusion

Buy if you want a cold, restrained Doppler that still pops in third-person, you will inspect every listing for pattern placement, and you are fine paying a premium for FN/MW-only wear. Pass or wait if you need warm ruby/sapphire drama (other phases), hate micromanaging float, or you cannot verify Phase 3 on the listing—mix-ups with Phase 1/2/4 are common in search filters.

Release timeline

Phase 3 Doppler landed 2015-01-08 with the Full Spectrum update—the same patch that added the Chroma Case and new knife finishes. Any serious price history on Steam or C5GAME eventually anchors to that date.

Which case

It debuts with the Chroma Case. The finish is the third phase of the Doppler line; which knife model you get is whatever the case’s knife pool rolls. Before checkout: confirm phase + wear, not just the black-silver sparkle in a thumbnail.

Skin facts that affect price

• Wear band: 0.00–0.08 — only Factory New and Minimal Wear. No Battle-Scarred bargain tier.
• Designer: Valve.
• Look: marble undertone plus thick electroplate gloss; on knives the multicolor plate catches light hard in inspect and in hand.

What to check in inspect

Screenshots lie about lighting. In-game inspect is non-negotiable: where the color blocks sit, how the gradient breathes along the blade, and whether the “candy” read feels clean or muddy. The narrow float window makes tip and spine scuffs show up fast—MW vs FN often differs more at the edges than buyers expect. Filter and trade as am_doppler_phase3; do not let “Doppler” alone decide the deal. If you like cool metal over loud warm phases, Phase 3 is the disciplined pick that still steals glances when you swap knives mid-round.

Expert muttering

I treat Phase 3 as the “office wear” Doppler: less shouty than the warm phases, still flexy when the coat hits a good light loop. Because you only get FN/MW, people overpay for float numbers while ignoring pattern—then regret it in spawn. On C5GAME, sort by phase first, wear second, pattern third; on Steam, same order. And yes, that candy shine is gorgeous until your blade edge tells a different story at 0.07.
