I'll look at it, but I don't think that the bends are where
the weld is. The weld on that blade wasn't noticeable like
on the replacement, where I can hear it going over the wheels
and the saw frame dips when it goes past the work, as though
the blade is a little thinner (front to back) there. But it
sure could have been welded out of plane.

Are the blades with variable numbers of teeth (i.e. 10-14)
significantly better than regular blades?
