★ Butterfly Knife | Case Hardened is a classic balisong first obtainable from the Operation Breakout Weapon Case in 2014. This knife has been finished in a “Patina” style, with the Case Hardened finish: heat-treated steel blooming into swirls of royal blue, violet, and straw-gold across the clip-point blade. The dark handles with brushed metal inlays frame the iridescent colors and make the Butterfly’s fluid flip animations shine. Each pattern seed is unique: collectors hunt “blue gem” playsides with heavy cobalt coverage, while mixed oil-slick blends create dramatic, one-of-a-kind looks. In Factory New condition, the edge, spine, and latch area are pristine: no scratches, tip wear, or dulling, so the glossy oxide layer remains crisp and uninterrupted.
