OK - After some time messing with it, I have come to the conclusion that it is more trouble than it is worth. My hands are sliced to shreds. Too much prep. Glue, press, wait, tape, apply pattern, pray. When putting it back to back to make something - a regular blade chips out the bottom. A #0 reverse tooth did ok, but I dropped one piece and it cracked. Can't sand that out. The edges are too sharp and the corners are dangerous. It was worth a try, but - no thanks.
