I have dealt with Buckeye Engraving for many years. You actually get to speak to the guy who runs the place and probably makes the stamps. They will make sharp or blunter angles on the stamps,depending if they will be used on wood or metal. You can select any font you can find on a computer,or make up your own logo,and they will make it for you.
Years ago I used the Hansen tap and die co.,but it got to where I could not speak to the man in the stamp shop. There was a stubborn ,egotistical female I could not get past. When she asked "What's a serif"? I gave up on them. Why put an unqualified idiot in charge?
