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

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.
