B&D replaced my old Pirhana circular saw blade after one of its carbide teeth flew off, but the new blade looks very different. The original one was Teflon coated, and each carbide tooth was curved concave on the front, but the new blade is plain or chromed steel, the teeth have flat faces, and there are more teeth.
Why did B&D changed from curved to flat carbide teeth? The curved ones seemed to give smoother cross cuts than other carbide blades having the same number of teeth.
Should I get one of the Mr. Sawdust or Oldham blades? I want smooth cross cuts but reasonable cutting speed.
