Gut Knife | Doppler Sapphire (Gut Sap) 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 creating gradient transitions. The design of the skin resembles the texture of the sapphire. The handle is made of wood and remains unpainted.
Float Value of the skin ranges from 0.00 to 0.08, which makes Gut Knife | Doppler Sapphire available only in Factory New and Minimal Wear condition. At levels of wear close to the maximum, the knife has noticeable scratches and abrasions located on the spine and on the corner of the blade close to the handle.
The pattern index affects the texture overlay. Special or rare variations of the pattern are absent.
The quality of Gut Knife | Doppler Sapphire is Covert. The skin has a StatTrak option and is not the rarest but the most expensive phase in the “Gut Knife | Doppler” series.
“Doppler Sapphire” is one of the most popular skins for Gut Knife. The skin has a very large number of fans, but due to a high price, it is rarely seen in the game.
