Constant Sub Katana clay tempered unpredictable — exactly how itThe Constant Sub Katana is a rare blade forged not just with steel, but with deliberate complexity. At its core lies Shihzume gitae (), an advanced traditional forging method where the hard steel core is sealed from all four sides with softer layers. This structure offers remarkable balance: strength where it matters, and resilience where its needed. Its a forging style rarely seen today demanding, precise, and absolutely beautiful in cross section.
