What Makes a Case Hardened Pattern Valuable?
The CS2 Case Hardened finish applies a randomized blue, gold, and purple patina across 1,000 possible pattern indexes per weapon. The market only cares about one thing: how much clean blue lands on the most visible surfaces — the blade face on knives or the top receiver/barrel on rifles. A pattern with 95% blue on the playside can be worth 50x more than a pattern with 5% blue, even if both items share the exact same float and skin name.
Community tools like CSBlueGem rank every pattern into five tiers. Tier 1 patterns carry $20k+ price tags for knives, while Tier 4 and 5 are effectively market price. This tier system is the universal language for Case Hardened trading, and platforms like CSBoard's Karambit Case Hardened listings let you sort inventory by these exact tiers.
