What Makes Karambit Case Hardened So Special?
The Karambit is one of CS2's most iconic knife shapes, and the Case Hardened finish adds a layer of rarity due to its randomized pattern. Each Karambit Case Hardened gets a unique pattern index (0–999) that determines the amount and placement of blue, gold, and silver on the blade. The community prizes blue-dominant patterns, often called 'Blue Gems,' with the most desirable ones showing 90%+ blue on the play side.
Patterns are classified into tiers: Tier 1 (top 1–2%), Tier 2 (next 5–10%), and Tier 3 (the rest). Tier 1 patterns like #387, #470, and #661 can command six-figure prices, while Tier 2 patterns offer a more affordable entry point with still-impressive blue coverage.
