A double-edged sword with a similar design to a katana, but featuring blades on both ends of the hilt, is often referred to as a "naginata sword." The naginata sword is a polearm weapon originating in feudal Japan, typically consisting of a long wooden shaft with a curved, single-edged blade attached to one end. The blade of a naginata can be double-edged, providing cutting and thrusting capabilities, though the overall design and usage differ from that of a traditional katana.
