The blade and the front part of the handle are 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 blue creating gradient transitions. The design of the skin resembles the texture of the sapphire. The main part of the handle remains unpainted.
Float Value of the skin ranges from 0.00 to 0.08, which makes Navaja 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 the front part of the handle.
The pattern index affects the texture overlay. Special or rare variations of the pattern are absent.
