Rupert sharpened his first knife when I was just beginning to toddle 
Or was that a question about practicality of that sharp edges? I love Ken's likening of the science of sharp we pursue here with auto-racing industry, Ken said: "Numerous automotive innovations which began in auto racing would have seemed like overkill for driving the family sedan at fifty miles per hour. Today many of those innovations have become part of everyday family auto technology... I can see these advancements gradually filter into everyday sharpening. "
People who tried MDF wheels mention scratches, MDF is not suitable for fine honing.
Unlike the pressed paper, MDF surface is pockmarked (microscopically), trapping abrasive particles into larger conglomerates; as these break and form again you get random scratches on the finish.
Another argument against MDF and pro paper is the paperwheel compressibility: use of a compressible substrate helps to avoid formation of the burr that is produced by edge-trailing honing on a hard substrate.
