counterbalance
A device on a board cutter, or similar device,
consisting of a bar or rod with a weight or
weights that are adjustable so that they can
increase or decrease the counterbalancing effect
on the blade. The rod or bar is an extension of
the knife, and, by the action of gravity, works to
prevent the knife from dropping and also assists
in raising the knife following the cut. Although
originally intended to enhance the usability of
the blade, the counterbalance today is considered
to be more of a safety device than a functional
part of the cutting operation. (145 )
