I have an old straight razor which I would like to do up a bit. It is in pretty good ocndition overall, but on the blade there are these little black spots, usually in bunches (looks like the spray option in MSPaint). I gather these are known as pitting? Anyway, I tried polishing them out, but I'll be sitting here forever if I want to do it that way. I do have some wet&dry sandpaper, which goes up to grit 1500 I think. Can I use that, and then try to polish out the scratches at the end?

I don't have a dremel, or any other tool like that, so I'll be doing this by hand.

I have checked out the sanding tutorial here, but last time I tried that it took forever to get the scratches out, so I just want to ensure there isn't anything else I can do first.
