15年物のニッパーを研ぎ直して鏡面加工してみた

My brother bought these GISUKE nippers over 15 years ago and they are still in use. I'm going to try to polish them to a mirror finish and sharpen the blades. There was no information on how to sharpen nipper blades, so I'm just trying to figure it out. I'm on Twitter.   / diy20414383  . ■Introduction to the tools used.
