How to give an unused knife a shiny mirror finish with sandpaper

I made a video on how to mirror finish a 20-year-old German Solingen that has not been used for many years.
This time, I manually mirrored it using sandpaper for about 2 hours.In the video, I used cork to polish the knife without worrying about cutting my hands.
If this is well received, I would like to teach you a simpler and more reliable mirror finish method using a Japanese knife.
Please ask questions about the mirror finish and even questions. I definitely want to respond.
