Which tools are best for working on Air guns?

I’m not sure its soft that you want. The stainless steel seems to glide across the bluing and scrap off the rust? I don’t see the stainless steel harming the bluing at all? Its a bit counter intuitive?

I suppose it depends on what you are rubbing. For instance for de-leading barrels, you get little patches made from bronze/copper - softer to the barrel.
