What does full tang mean in a katana?

Full tang means the steel blade extends completely through the entire length of the tsuka (handle) rather than stopping partway. The tang is secured by one or more mekugi pegs — traditionally bamboo — passing through aligned holes in the handle and the tang itself. This construction creates a single unified structure, which distributes weight along the whole sword rather than concentrating stress at a joint between blade and handle. Collectors recognize full tang construction as the correct standard for any seriously made Japanese-style sword. Partial tang or rat-tail tang designs are common in inexpensive decorative pieces and can be identified by significantly lighter handle weight and a visible seam or cap at the butt of the tsuka.

What makes a Damascus steel tachi different from a standard katana?

The tachi predates the katana historically and is distinguished by its deeper curvature, slightly longer blade, and its mounting style — it is worn suspended edge-down from cords rather than thrust through a sash edge-up like a katana. When forged in Damascus steel, the tachi blade displays the characteristic layered grain pattern created by folding multiple types of steel together during forging. This combination gives you a collectible piece that pairs one of the oldest Japanese sword silhouettes with the visual complexity of multi-fold steel, resulting in a display sword with both historical significance and striking surface detail.

What makes a tachi different from a katana in design?

The tachi predates the katana and features a deeper curvature along the blade, a longer overall length, and a mounting style designed for wear edge-down suspended from the belt rather than thrust through it. This edge-down orientation influenced every element of the koshirae - from the positioning of the menuki on the handle to the direction the saya lacquer is applied. On a properly assembled tachi, the suspension fittings called ashi attach to the saya so the piece hangs at the correct angle when displayed or worn. For collectors, this means a tachi's visual presentation is fundamentally different from a katana even at rest on a display stand - the curvature reads more dramatically and the full koshirae tends to appear more ceremonially elaborate.

What display hardware is appropriate for a long blade katana?

Updated Feb 2026

Long blade katana require display hardware chosen specifically for their extended blade length and greater weight compared to standard katana. For horizontal wall display, two-bracket support is recommended rather than a single central bracket: position one bracket at approximately one-quarter of the blade length from the handle and a second at approximately three-quarters of the blade length to distribute the weight along the blade without concentrating it at a single point. Both brackets should be rated for the weight of a large-format blade - typically 4 to 6 pounds for a heavy odachi-scale piece - and should be anchored into wall studs rather than into drywall alone. For the longest pieces in this collection, a dedicated floor display stand positioned diagonally is the most practical solution, as it accommodates the blade's full length within normal ceiling heights without wall hardware limitations. Peg spacing on wall brackets should be adjusted to match the specific blade's length rather than using a fixed configuration that may not provide adequate tip support for extended blades.
