Master Guide to AK-47 Case Hardened Blue Gem Patterns & "The Scar" #661

All other patterns, except for #661, are divided into three tiers by the amount of blue colour on the weapon finish. But at the same time, this blue is taken into account only on the central part of the gun's case and the mag. Blue spots on the barrel's end and the buttstock's back do not affect the tier.
The AK-47 Case Hardened features several highly sought-after Blue Gem patterns, which can be categorized into different ranks based on their blue coverage on the central part of the gun's case and magazine. The legendary "Scar" pattern stands alone as the most valuable AK-47 Case Hardened pattern in existence.
This is an AK-47 Case Hardened with pattern #661. It got its name in honour of a small yellow stripe on the side. Look, it's placed just above the gun's clip. This is an extremely rare CS2 skin. Overall, there are only 127 such skins that the CS2 community knows of, and only ten of them are Factory New.
The ranking system focuses on blue coverage in the central areas of the weapon, making these patterns highly valuable and sought after by collectors.
