Here's my opinion.

Don't breadknife. It takes sooooo much work to bring a bevel back to a razor that has been breadknifed.

You can use a metal polish on the blade, such as Maas or Flitz. They both work nicely, although I prefer the Maas. They can also work on scales, although be gentle because they are abrasive. Alternately, a rough cloth and soap/water might help. For the inside, grab a pipe cleaner. They work really well.

As for the honing, I would seriously recommend that you find someone local (and we have quite a few members in and around the UK) to either hone or help you hone that razor. Some wedges can be absolutely no fun. If it were me, I'd send it out.

Hope this helps a bit,
