The chokuto (or occasionally jokuto) was a Japanese straight sword, crafted in bronze, with a large round pommel. The blade could either be single or double edged, and due to its length, was wielded with both hands.

These weapons are thought to have been influenced by the Chinese/Korean style swords and was popular between 300-900 A.D.. after which chokuto were used in a purely ceremonial setting, and were practically superseded by the tachi.
