Generally the jaws of a vise grip are curved so that the actual clamping
point would be well inboard of the teeth (especially a plywood blade's small
teeth). Alternatively, your idea of using wooden pads would also mitigate
damage to the blade's teeth. This method doesn't seem any more damaging to
a blade that ramming wood into the blades to stop it turning.

Just curious, but does a plywood blade have separate welded teeth or is it
just a one-piece stamped steel disk with teeth cut into it?

One method of holding the blade while truning the arbor nut is to clamp
the
blade with vise grips (as a caliper grabs a rotor on a car). The vise
grips
will not pass thru the throat plate opening and will prevent the blade
from
spinning while you apply pressure to the nut with a wrench. It will
also
free up your other hand.

Tom,

I thought about that solution, but wonder if clamping the blade may cause
other problems, such as bending the blade, affecting tensioning or
cracking/weakening a weld on a tooth.

I also thought of sandwiching the blade between two pieces of wood, then
clamping - but once again, I am not comfortable with the idea. Any experts
on blades out there care to comment?
