Jeff, almost, (if not all) major blade mfr's. manufacture a blade for mitre and radial arm saws, and they aren't special order. It's true that not all catalogue companies (such as Amazon, etc) show them in their catalogues or stock them, but they are still widely available. I know for certain that Freud, Forrest, Hitachi, Dewalt, Infinity, etc make them. They are sometimes listed as Mitre Saw blades, and if you get to the mfr's spec pages, you can see which hook angle they have, and this does vary from mfr to mfr., usually from 0* to -5 or -8* IIRC. Those same Spec pages will also give the Kerf thickness in thousandths so you can see if they are a thin kerf or full (or close to full) kerf blade, full kerf of (normally 1/8") being .125", (for those who don't know).
