T10 Clay Tempered Japanese Naginata - Real Hamon, Blue Lacquer Saya, Handmade Polearm

This T10 carbon steel naginata is built around one defining proportion: a 52cm handle paired with a 21cm nagasa, 31 inches overall. The extended handle is what defines the naginata polearm format - the long tsuka shifts the balance point back and creates the leverage geometry that distinguishes it from a standard sword. In this piece, the result is a compact, display-ready form that carries full naginata proportions at a manageable size.

The blade is T10 steel, folded prior to clay tempering. Folding distributes carbon content through the billet; the clay-tempering process - coating the spine before water quench - creates differential hardness between the edge and the spine. The hamon line that results is a physical record of the tempering process, not a cosmetic addition. It runs along the lower edge of the blade and varies in character across its length, as genuine hamon does.

The bamboo-themed alloy tsuba is a considered detail. Bamboo is historically associated with naginata fittings - it was used in the poles of training and ceremonial naginata, and the motif echoes that material connection. Set against the blue-lacquered saya with marble-pattern finish, the overall color palette is distinctive: natural steel, bamboo motif, deep blue lacquer.
