Master Guide to Karambit Doppler Phase 4 Max Blue Patterns & Tier Classifications

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, dark blue and black creating gradient transitions. The handle remains unpainted.
The pattern index affects the ratio of colors as well as the location of blue, dark blue and black areas. Pattern variations with a predominance of blue on the play side of the blade are titled "BTA Blue". Knives with only blue color on the blade resemble Karambit | Doppler Sapphire and are titled "Max Blue".
For Karambit Knife Doppler, the Max Blue pattern is very well placed, since the dark blue (black) part of the pattern is located under the handle of the knife. Karambit Doppler Phase 4 is the best among rare patterns, since the Max Blue patterns are located on both the Play Side and Back Side.
