Re. honing: If there's no rust around the edge, you can protect it by folding, say electric tape over it - carefully! Don't do it tight around the edge, but leave some slack.
If you don't protect the edge and want to polish the razors, be VERY careful. This is never a good idea. In fact, I kill the edges intentionally before starting any work on the blade faces. Too many cuts, you know... :(
