Just got my Magna-matic 9000. I can see that it will indeed save some time with superior results. I only played with it for a few minutes, but wondered if there are some simple principles to get a razor edge? Any suggestions on blade angle, dressing blades and so forth to accomplish this would be great. I was fooling with some fairly used blades, and got them to look awsome in a short amount of time, but was not getting the blade ground down to the very edge. They were sharp, but I want to be able cut off fingers just by picking up the blade. Can you say Scalpel?
