AK-47 | Case Hardened appeared in CS:GO on August 13, 2013. The skin is contained in the CS:GO Weapon Case that was added to the shooter in “The Arms Deal” update.

AK-47 | Case Hardened is remarkable for its pattern of multicolored stains that look like gasoline ones on the water surface. This pattern is the result of the case-hardening process of a metal object, which changes the composition and structure of the surface layer and makes it harder.

The pattern index determines which colors will dominate on the rifle’s surface, and this directly affects the skin price. The versions with blue receiver covers (e.g., indexes 321, 661, and 670) are especially valuable – shades of blue on other rifle parts don't significantly affect the price. Versions with shades of yellow have the most modest price.

Float Value of AK-47 | Case Hardened can vary from 0.00 to 1.00, making the skin available in any exterior quality category. As the quality deteriorates, the skin darkens, but there are no scratches or abrasions on the weapon's surface.

AK-47 | Case Hardened belongs to the “Classified” rarity grade and is available with the StatTrak kill counter. The skin is popular among CS2 players.
