From Aoi Art: A sturdy and well-forged piece with a good meaty feel. This piece, weighing 855 grams, is a healthy example, showcasing the distinctive beautiful steel grain of Hizen, with a finely packed ko-nie (small particles). This Hizen steel was carefully protected by the Nabeshima clan and lasted until the late Edo period. It is impressive to see the Tadakiyo lineage, from the 1st to the 8th or 9th generation, enduring and continuing without the interruption.
