How does a ninjato differ from a katana in terms of design?
Updated Mar 2026
The most immediate difference is profile geometry. A katana features a pronounced curved blade — typically between 60 and 75 cm — designed to produce a drawing cut during unsheathing. A ninjato, by contrast, has a straight or very slightly curved single-edged blade, usually shorter in overall length, with a squared or simply shaped tsuba. The ninjato's straight profile gives it a visually stark, architectural quality that collectors often find distinct and display-friendly alongside curved sword forms. The shirasaya mounting style seen in this collection further emphasizes the clean linearity of the ninjato silhouette.
