What makes a ninjato different from a traditional katana?
Updated Mar 2026
A ninjato is distinguished primarily by its straight or near-straight blade geometry, as opposed to the pronounced curvature of a katana. This results in a different balance point - weight sits closer to the hand rather than distributing forward along a curved edge - which changes how the piece presents on a stand or wall mount. The tsuba on a ninjato is often square or rectangular rather than round, another visual marker collectors use to identify the form instantly. These swords are collected and displayed as representations of a distinct school of Japanese blade-making tradition, separate from the curved tachi and katana lineage.
