If I'm reading your statement correctly, you say you want a blade that cuts on the up stroke. My first question is why? The blades are designed to cut on the down stroke to help hold the wood down to the table. As said, there are some blades that have about 3/4" of up-cut teeth at the bottom to create a cleaner cut on the underside. Less fuzzies that way. I would suggest that if up cutting is essential you turn your piece over and cut from the bottom side.
