What is a kodachi sword and how does it fit into Japanese sword history?
Updated Feb 2026
The kodachi - meaning "small tachi" in Japanese - is a shorter version of the tachi, the long curved sword that preceded the katana as the primary sword of the Japanese samurai class. Where a full tachi might measure 60 inches or more in overall length, the kodachi is a significantly more compact blade, typically falling between the tanto and the wakizashi in the Japanese blade length hierarchy. Historically, the kodachi was used across a range of martial contexts during the feudal period and was associated with both civilian and military use, valued for its compact size and the speed and control its shorter length allowed compared to a full-length tachi or katana. In the context of modern collecting, the kodachi is prized as a historically significant blade type that combines the visual character of traditional Japanese sword craftsmanship - curved single-edged blade, traditional fittings, matching scabbard - with a scale that offers practical advantages for display and handling. Each piece in this collection is built to the full construction standards that serious collectors expect, including full-tang construction and high-carbon steel blade forging.
