I ordered a couple of these blades from Mike Jackson, over at Leitz. They are the very best blades I have ever used to cut birch plywood. Absolutely no tear out and very quiet running. Only paid $25 each, plus freight. Bought a total of five blades, including the HO Shumacer & Sohn blades, and they were $93 delivered to my door. Go over to Woodnet.net and do a search for excesstooling as the poster and it will lead you to Mike.
