Karambit | Case Hardened (Field-Tested) is a premium knife finish that debuted with CS:GO’s Arms Deal Update in August 2013, appearing as a Rare Special item across early Weapon Cases. The blade uses the “Patina” style: heat-treated steel that produces unique swirls of blue, purple, and gold. Every pattern seed is one-of-a-kind, and high-blue “blue gem” faces are especially coveted by collectors. The curved talon profile features a matte black handle with finger grooves and a safety ring for a secure, tactical grip. In its Field-Tested condition, the skin shows moderate wear, with visible scratches and slight fading along the weapon’s surface. Beloved since launch and consistently ranked among the most popular knives, Karambit | Case Hardened remains in high demand for its rarity, iconic silhouette, and chase-worthy pattern variability.
