Pattern
The metallic body of this assault rifle carries clear traces of a hardening process. It causes a very specific texture pattern: a gray and yellow background with “clouds” of blue. Different pattern indexes of AK-47 | Case Hardened affect the positioning and quantity of the blue metallic parts. The rarest and most valuable skins of this type have a lot of blue on the top part, and they are called Blue Top. Fully blue Case Hardened skins are absolutely unique in Counter-Strike.
