Welcome to the forum. Mind if I ask what you mean by "old school fashion"? The craft has been around for thousands of years, so a time period would be helpful if we are going to do you any good with advice. Also be aware that, although doing things using antiquated methods is fun and educational, there is a reason they are antiquated. opting for a rough rock instead of a belt grinder may be a heck of a cool thing to try, but PLEASE don't limit yourself unnecessarily. Again, welcome to the forum and the craft.
