Some people just don't know how to tell a joke.
- Of what metal are the blades made?
- What sort of damage has been done and to what extent?
- What are your expectations in terms of polishing?
Kits for polishing Japanese blades aren't going to help deep scratches and dings unless you have 300 years to work on them and you're not prone to tendonitis. Depending the metal and construction, bead blasting might be the best alternative. It will hide a lot of damage and a useful finish.
