Well this seems to almost have become a Paperwheel vs belt grinder thread. I'm another in the belt grinder camp. A leather belt is a must for one, I used one without for a few years bit the bullet and got one. I could kick myself for not getting one right away. Only learning I needed with the belt grinder was to not pull the tip across the belt. That will round the tip. I was a long time hand sharpener but really there is nothing to learn useing a belt grinder. I have used a few of the clamp and jig systems and they work great. Truthfully if you learn the basic steps of sharpening you can use just about anything to sharpen with. Now that I really know how to sharpen I prefer bench hones, and the belt sander. There really is no majic to any system or method, they all will work. Some work a little faster and some work a bit better but that is mainly based on how much of a polish and low of an angle you can get.
