Rust Eraser Sabitoru （Rough,Medium,Fine)3-piece Set with Polishing Cloth

Pricey but works great.

These rust erasers are incredible. They simply rub them with the grain and they scrub the rust away leaving no trace. The different sized grits enable you to match the polish level of the metal you're cleaning.

Great product for removing scratches and for cleaning whetstones. Much better and cheaper than a conditioning stone. Does not replace a nagura stone for developing a slurry for polishing knives. This product lasts for a very long time.

I was amazed by how well these worked. follow the directions.. (witch i will admit is hard since they are written in Japanese) but there are youtube videos and clues in the listing about it. they work like magic... BRAVO! well damn done!

Useful item from Japan, would be better if product info and instructions were provided in English and delivery didn't take 4 weeks.

Good useful product

It is useful for clean the sharping stones for sure.

These work like a dream for removing light rusting - give a beautiful finish
