This video isn’t about kintsugi but kasugai, staple repair. 鎹 修理,
This video shows sharpening of the tips, the parts that will go into the holes in the ceramic body. I am using a flat file. The staples are held in place by a mini vise. These staples are the ones in part 2 that are the 3rd set I made, from steel.
I will probably make 1 more set from pure copper.
