Really, no switching?! I gotta get one. Do I have to get the WWII model, or is there one made after 1945?
I never can tell if you are just being a smart ass or joking Robert... If I am about to rip a bunch of 6/4 hardwood, I may put a thin kerf rip blade in the saw, just because it's faster and I might get a couple more board instead of a larger pile of sawdust, but the WWII (wood worker II) stays in the saw. I was using a Frued 80T ATB (ultamate line), and find the end grains are smoother with the WWII.
I do have a blade I use for melamine, or any sort of coated sheet good like laminate where chip out is a concern. It's an older Delta triple chip.
