I have two issues with my Wusthof Classic Ikon knives.
1. About a year ago, I used the hard side of what was ostensibly a scratch-safe sponge, on my chef's knife, and it scratched up one side of it. This doesn't affect its use and it's not immediately visible unless you know it's there, but it does bother me. Is there anything that can be done about this?
2. My paring knife is only a month or two old, but I believe I left it in a plate filled with water, in my sink, for a few hours, and now there is rusting on the handle—particularly in the areas around the rivets and between the tang and the handle, at the rear. Rubbing with soap doesn't help much. What's safe to clean it with?
