What makes a kodachi katana different from a standard full-length katana?
Updated Feb 2026
The primary difference between a kodachi katana and a standard full-length katana is blade length and overall scale. A full-length katana typically measures between 38 and 42 inches in total length with a blade of 27 to 30 inches. A kodachi katana is shorter across the board - its blade falls below the standard katana range, producing an overall length that is meaningfully more compact and easier to display in typical home environments. Beyond this size difference, both types share the curved single-edged blade profile that defines the Japanese katana tradition, and both feature the same full set of traditional fittings: tsuba guard, ito-wrapped handle over a same base, and a saya scabbard. Full-tang construction is standard for both. The kodachi katana is the choice for collectors who want the full visual and material experience of a traditionally fitted samurai sword at a more manageable scale - either as a starting point for a collection or as a companion piece to a full-length katana in a multi-piece display arrangement.
