I know there's soem kind of sharpening guy/place on Cornwallis Rd just shouth of 42. I've seen the sign (shaped like a saw blade). Don't know anything about the place, though. I think Hudson's Hardware does it, too, but they're in Garner.
I'm probably telling you something you already know, but it's very easy to do it yourself for just a few $$. Hudson's or Lowe's has the tools a guidance you may need.
I keep forgetting about them being there now. Thanks for the reminder. I need a small piece of plexiglass cut, so I may head over there Saturday.
