I have been using my set up I bought from The Art Of Shaving and want to step it up to a straight. I learned to shave on one when I was about 15 so its been about 10 years. I was looking online for a used one and want to restore it, throw on some homemade scales, and go from there.

My question is what are the different sizes and what do they do differently than the others?

Other than that I have been looking around on here and have found most of my answers already.

Thanks,
Mike
