The Japanese Chokuto Sword
Chokuto Sword (or Chukandomowas) were straight and single-edged, although sometimes partially double. The Chokuto Sword is a copy of a sword that was originally brought into Japan from China and Korea during the 4th and 5th centuries.
The Chokuto Sword was developed before differential tempering technology evolved. They were made with a hira-zukuri or kiriha-zukuri tsukurikomi blade style.
The Chokuto was hardly used in battle due to the fact that is was shown to be less effective against other swords which were lighter and had curved blades. Over time, the Chokuto came to be used as a temple offering sword.Similar with the katana, just not curved but straight. Found before the Heian era before the Japanese found the sword arch technique (which was a unique way.)
Because the straight sword is difficult to use and rarely used in combat. After the discovery of the katana, chokuto still produced but mostly serves as a ceremonial sword.
