The cutter size looks like its 1/4 if i measured it right. And some of the nickel plating is coming off to. You should see everything in the pictures if not please don't be afraid to ask questions. All in all this is a very nice collector tool for a beginner or for anyone.
Or i can send more pictures if need to be. Make me an offer i can't refuse. I reserve the right to resale this item within 3 days if no contact or paymen.
