About ★ Flip Knife | Case Hardened
The ★ Flip Knife | Case Hardened in Battle-Scarred is the entry-tier price floor for Flip Knife pattern hunting. Released with the original 2013 knife collection, Case Hardened on Flip Knife provides the cheapest possible Tier-1 blue gem research opportunity on a launch-era model.
Why BS for pattern research
BS is the lowest practical price point where pattern verification still works. Lower BS floats keep the boundary between blue and yellow oxidation legible enough for Tier identification — even if the polish softens. Many serious blue-gem hunters cycle through 10-20 BS Flip Knife seeds before identifying a Tier-1 candidate worth upgrading to MW or FN.
Pattern tier mechanics
Standard tier pricing applies: Tier-1 BS Flip blue gems trade at 4-6× generic BS premium.
