Tooth design of blades can make a big difference in the type and quality of the cut. Since for a 10" saw, there are a multitude of blades that can be just installed with a washer and a nut, knowing what to use and what it looks like may be of some help.
If you have a stack of blades or acquire a blade with a tool, you can make a quick visual inspection of the teeth and figure out what you have. Blades for the miter type saws and the RAS's work best if they are negative hook. It's easy to figure out if you don't know. Envision a straight line from the center of the arbor hole up past the front face of a tooth. If the tooth tips backward from that line it's negative hook. You could use a ruler instead, and just lay it on the blade and see how the face lines up on the ruler edge. If the face tips toward the ruler...it's a positive hook. If it lines up, it's neutral.
This chart may be of some help.
