Mass And Fritz are both metal polishes much like brasso but one's that most of the guys here recommend. Toothpicks also work well along with the dental floss. I would highly suggest you send the razor out, at least just one time as I said. After that you can always try and sharpen your blade from there but then you will know what it is supposed to shave like, and have a good number of shaves under your belt. First thing to focus on is stropping, as that is more important then a barber stone / etc for keeping your edge keen. As for maintaing the edge that a strop wont take care of there are many ways in which you can do so. A strop with one side pasted with Chromium oxide, will work for quite some time, then of course after that no longer works, there are many options and everyone has their own preferences such as a barber hone, coticule, 10k, 12k or other finishing stone etc. Do some searching on keeping your blade sharp and you'll find a tone of information, you will need to find what works best for you and your budget.
