What is the difference between a ninjato and a chokuto?

Both are straight-blade Japanese swords, but they come from different eras. The chokuto is one of Japan's oldest sword types, dating back to the 3rd century with roots in Chinese blade-making traditions. It predates the curved katana and tachi. The ninjato is a more modern concept associated with the shinobi tradition, typically featuring a shorter blade with a square tsuba. Many collectors appreciate both styles, and our chokuto ninjato pieces combine elements of both — an ancient straight-blade profile with ninja-inspired fittings.
