Photo essay on Yoshindo Yoshihara and Yoshikazu
Joe Pierre posted a nice link on FB (https://www.facebook.com/groups/1725109617721256/) to a photo essay (text in Japanese) on the Yoshindo forge. Some nice pictures of the forge in operation, and photos of blades by four generations of the family. Enjoy!
