1065 Carbon Steel Shirasaya Katana with Black Matte Hardwood Saya and Gold Habaki Collar

This shirasaya katana features a full tang blade forged from 1065 carbon steel, hand-finished to a chrome polish with a hardness of 62 HRC. The 28.74-inch nagasa carries a visible hamon line along its edge - a natural result of differential hardening that gives the steel both flexibility in the spine and firmness at the cutting edge. The tip comes to a clean, precise point, as seen in the kissaki detail.

The handle follows traditional shirasaya construction at 10.62 inches, with black real rayskin layered beneath the hardwood exterior. This inner rayskin layer adds grip texture and structural reinforcement, while the smooth black hardwood outer surface maintains the clean aesthetic that defines the shirasaya form. The transition from handle to blade is seamless and uninterrupted by a tsuba guard.

At the junction of blade and handle sits a gold-tone alloy habaki collar with a finely knurled diamond crosshatch pattern. This collar serves both a functional and decorative role - it locks the blade securely within the saya while providing a striking visual accent. The warm gold tone against the black handle and silver steel creates a deliberate three-tone contrast that anchors the entire design.

The saya is crafted from hardwood with a matte black lacquer finish, measuring 29.92 inches. The surface has a subtle textured grain visible up close, and the koiguchi (mouth) fits snugly around the habaki for a secure, satisfying draw. The minimalist profile - no sageo cord slot, no ornamental fittings - keeps the silhouette sleek and undistracted. Explore more options in our Black Shirasaya Katana Sword collection.

At 40.55 inches overall and 2.8 lbs, this katana strikes a balanced proportion between blade length and handle control. The Full Tang Shirasaya Sword construction runs the steel through the entire handle, contributing to structural integrity and natural weight distribution. Whether displayed on a stand or held in hand, the clean lines and restrained palette make this a refined addition to any collection.
