Variable teeth 10" table circular saw blade?


Really funky looking teeth pattern unlike a combination blade - so what's the advantage in using this type of blade?

How could you tell if the blade exhibit harmonics? Never had that problem before but, on the other hand, if I don't know what I'm looking for I couldn't tell the difference between the harmonics between the blade or the motor.

Woodworkers Journal did a comparison of 10" blades and that particular blade didn't do very well, (scored a 16 for overall performance). Forrest WWII performed the best(scored a 22 for overall performance), but they recommended two other blades because they were less expensive and performed almost as well. bc
