What makes the Kusanagi a chokuto rather than a katana?
Updated Mar 2026
The Kusanagi no Tsurugi that Sasuke wields is a chokuto — a straight, single-edged blade modeled on pre-Heian period Japanese swords that predate the curved katana by several centuries. The katana's iconic curve (sori) developed over time as swordsmiths discovered that a curved blade was more effective for drawing and mounted use. The chokuto's straight profile is historically older and geometrically simpler, which makes it visually distinctive in a landscape dominated by curved designs. In collectible form, this straight silhouette requires more careful scabbard fitting since there is no natural curvature to create tension and hold the blade in place — quality replicas address this through precision-fitted saya construction.
