About ★ Survival Knife | Case Hardened
The ★ Survival Knife | Case Hardened in Factory New brings the classic Case Hardened pattern lottery to the Shattered Web knife generation. Released with Operation Shattered Web (November 2019), the Survival Knife is a serrated single-edge fixed blade designed as wilderness equipment — and Case Hardened's blue-yellow oxidation pattern has unusual room to develop on its broad blade.
Blue gem hunting on Survival Knife
Same Tier mechanics apply: Tier-1 blue gems (>90% blue play face) command 5-8× generic premium; Tier-2 (60-80%) at 1.5-2.5×; Tier-3 (notably blue-dominant) at 1.2-1.5×. The Survival Knife's flat play face makes pattern verification straightforward — no curvature distortion.
FN as the verification tier
FN preserves the boundary between blue and yellow oxidation zones knife-edge sharp. For Tier-1 verification this is required — pattern tier confirmation depends on color separation that wear blurs out. MW is the secondary tier; FT and below are pattern-research only.
