About ★ Navaja Knife | Case Hardened
The ★ Navaja Knife | Case Hardened in Factory New is the cheapest FN Case Hardened entry on a Horizon-era folder model. The Navaja's compact blade concentrates Case Hardened oxidation patterns in unusual ways — pattern variance reads compactly but distinctly.
Pattern hunting on Navaja
Standard Tier mechanics apply: Tier-1 blue gem (>90% blue play face) at 5-7× generic FN premium, Tier-2 (60-80%) at 1.5-2.5×, Tier-3 (clearly blue-dominant) at 1.2-1.5×. The Navaja's small play face means blue gem verification is harder at a glance — verify with multiple inspection angles.
FN as the verification tier
FN preserves the boundary between blue and yellow oxidation knife-edge sharp. For Tier-1 verification on a small canvas like the Navaja, FN is functionally required.
