Flip Knife | Doppler

Origin Story

The Flip Knife | Doppler, released on January 8, 2015, with the Full Spectrum update, features a blade painted with black and silver metallic paints using a marbleizing medium, then candy coated. This finish is widely recognized as a premium knife skin and a status item within the community, thanks to its deep, glossy colors. The Doppler finish is known for its distinct phases, which exhibit varying hues of blues, purples, and blacks, with some phases revealing silver marbling. Its visual appeal and collector desirability are often compared to other luxury finishes like Fade and Marble Fade knives.

Drop Chance

Flip Knife | Doppler 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 0.08. Exteriors: Factory New, Minimal Wear. StatTrak is available in FN, MW.

• Factory New ($468.13): This tier features maximum gloss and color depth, ensuring the Doppler marbling looks rich and reflective across the entire blade, with edges retaining full color and shine. This is considered the premium cosmetic tier, often targeted by collectors and high-budget buyers.
• Minimal Wear ($622.84): Overall very similar to Factory New, this tier retains the same Doppler colors and pattern, showing only subtle loss of gloss or faint micro-scratches on close inspection, typically on the tip, spine, or edge. This is often considered the value pick, providing almost the same in-game look as Factory New at a lower price.

Model

Doppler uses the legacy Flip Knife model, introduced with Full Spectrum on January 8, 2015. The inspect animation and third-person appearance match the original CS:GO version.

Sticker Compatibility

The deep blues, purples, and blacks of the Flip Knife | Doppler pair well with blue or purple themed stickers, as well as iridescent holo or foil stickers. Minimalist white, silver, or black stickers can also complement its metallic base. However, knives in CS2 do not have sticker slots, so there are no sticker crafts for this item.
