That chef's plate is quite a deal, I am going to get one and have several diamond hones now.

Over the years I have watched sandpaper go UP^ in price and Diamond plates/hones go Down~
So much so it is shocking. If you look carefully at the price of sand paper retail from body and paint supplier's or hardware stores, you are NOt getting a deal, the diamond plates ARE THE Deal, they simply outlast the sandpaper by a wide margin. YMMV.
