Black Fan Katana — 1095 High Carbon Steel, Clay Tempered, Hand Forged, Full Tang, Battle Ready

This saya uses three premium natural materials rarely seen together on a production katana. The base is black piano lacquered wood for a smooth, durable finish. Both the mouth (koiguchi) and the tip (kojiri) are fitted with genuine water buffalo horn — a material prized for its density, natural luster, and resistance to cracking. Most distinctively, genuine sharkskin (same — 鮫皮) is wrapped at the koiguchi, the point where the blade enters and exits the scabbard. This is the same textured ray/shark skin used on traditional katana handles, applied here to the saya's most critical contact point. The result is a natural grip surface, a tactile signature that sets this scabbard apart from any standard lacquered saya, and craftsmanship that rewards close inspection.
