One of my students has a sword that was forged from what we suspect was a bell like this one at a Buddhist temple in Kyoto. It is pictured below. It is a beautiful sword and Furuya Sensei indicated that its smith, Masataka was one of the well known modern smiths who had studied under the two top smiths of the Showa period, Kasama Shigetsu and Takahashi Sadatsugu. The sword was made using metal from the main hall of the Narita Shrine in Narita.
It’s amazing how a material like metal can be reforged to make something completely different. Intense heat, and the pounding out of impurities, tempering, and polishing are all labor, time intensive skills. It makes me think how each one of us can reforge ourselves through training.
