Flip Knife | Case Hardened

Origin Story

The Flip Knife | Case Hardened features a distinctive blue, gold, and purple coloration achieved through a traditional color case-hardening process. This finish, applied to the blade, gives each knife a unique pattern, with variations in the amount and placement of the coveted "blue gem" areas. It was introduced to CS2 on August 14, 2013, as part of The Arms Deal update, marking an early entry into the game's cosmetic landscape. The vibrant and unpredictable nature of its pattern makes each Case Hardened knife individually recognizable.
