Flip Knife | Doppler Phase 4 (Flip P4) was added to the game on January 8, 2015, alongside the “Full Spectrum” update. The skin is available in all “Chroma” cases.
The blade of the knife is painted with metallic paints and adorned with a pattern of translucent wavy lines resembling smoke. The color scheme of the skin includes various shades of blue, brown and black creating gradient transitions. The handle remains unpainted.
Float Value of the skin ranges from 0.00 to 0.08, which makes Flip Knife | Doppler Phase 4 available only in Factory New and Minimal Wear condition. At levels of wear close to the maximum, the knife has noticeable abrasions on the corner of the blade close to the handle.
The pattern index affects the ratio of colors as well as the location of black, green and teal areas. Special or rare variations of the pattern are absent.
Due to a relatively affordable price, Flip Knife | Doppler Phase 4 became one of the most popular and common skins in the “Doppler” series.
