Bowie Knife | Doppler Ruby (Bowie Ruby) was added to the game on March 15, 2017, alongside the "Take a trip to the Canals" update. The skin is available in the cases "Spectrum" and "Spectrum 2".
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 uses various shades of red creating gradient transitions. The design of the skin resembles the texture of the ruby. The guard is painted brown, the handle is black.
Float Value of the skin ranges from 0.00 to 0.08, which makes Bowie Knife | Doppler Ruby available only in Factory New and Minimal Wear condition. Small abrasions are already present in different parts of the blade in Factory New condition. At levels of wear close to the maximum, small abrasions appear on the tip of the knife.
The pattern index affects the texture overlay. Special or rare variations of the pattern are absent.
The quality of Bowie Knife | Doppler Ruby is Covert. The skin has a StatTrak option and is not the rarest but one of the most expensive phases in the “Bowie Knife | Doppler” series.
“Doppler Black Pearl” is one of the rarest skins for M9 Bayonet and is highly valued by skin collectors. Due to a high price, M9 Bayonet | Gamma Doppler Black Pearl is rarely seen in the game.
