What makes tachi different from a katana in terms of design?
Updated Mar 2026
The tachi predates the katana and differs in several measurable ways. Tachi blades are generally longer, often exceeding 70 cm, and carry a more pronounced curvature along the entire length rather than concentrated near the base. Historically, tachi were suspended edge-down from the belt, which influenced how the curvature was shaped and how the fittings were oriented. The nagasa (blade length) combined with that deeper sori (curve) gives the tachi a sweeping, elegant silhouette that collectors find distinctly different from the katana's more compact, utilitarian profile. For display purposes, the tachi's longer form creates a stronger visual presence on a wall mount or horizontal stand, particularly when paired with a richly colored saya like the orange hardwood or rosewood finishes in this collection.
