I tried to restore the rusty Japanese kitchen knife I bought in the antique market.
After the restoration, it became the best sharpness.

First, I used a # 120 whetstone to flatten the knife surface and remove rust. Rust that could not be removed with a whetstone was removed with # 80 sandpaper.

Next, sandpaper was applied in the order of # 240 → # 400 → # 1000 to make the knife glossy.

Next, for the work of attaching a handle (commercially available) and a kitchen knife, I used a two-component epoxy resin.

Next, the blade was missing, so I fixed it again with a # 120 whetstone.
When the blade was repaired, I sharpened it with a # 1000 → # 2000 → # 5000 whetstone.

While I was sharpening with a whetstone, I damaged the body of the knife, so I applied sandpaper in the order of # 800 → # 2000.

Finally, I sharpened it with a # 8000 whetstone and used a polishing agent called "PiKAL" to make a mirror finish.

The old Japanese 10,000-yen note is reflected in the kitchen knife.

The method of peeling radish is a kitchen knife called "KATURA MUKI". It cut well.

Thank you for watching until the end.

Reflections
・ I used a commercially available knife handle this time, but from the next time I would like to use my own handle.
・ I couldn't completely remove the rust at the base of the blade, so I'd like to handle it properly from now on.
