I have a little cash set aside from a Christmas bonus and I was wondering what would be a better investment for right now; a silvertip badger brush or a norton stone and some diamond strop pastes? I have two razors that seem to shave pretty well (honed on a Tilly hone) but I'm sure they could be sharper. My brush is a $6 boar bristle special and seems to do the job, but the plastic handle is tacky to say the least Feedback would be greatly appreciated.
