KANAZAWA, Ishikawa Prefecture--A well-preserved ancient carpenter's tool that was at the cutting edge of Japanese manufacturing thousands of years ago has been discovered at the Yokaichijikata ruins in Komatsu in the prefecture.
The iron “yariganna” cutting pike plane, which is attached to a haft, is believed to be from about 2,300 years ago, the first half of the middle of the Yayoi Pottery Culture period (300 B.C.-A.D. 300).
