The height difference between the riving knife and
the blade allows the workpiece to pass over the
blade during non-through cuts (those in which the
blade does not cut all the way through the thick-
ness of the workpiece).
The riving knife also prevents the freshly cut sides
of the workpiece from pinching the blade and
causing kickback. For maximum effectiveness of
this safety design, the riving knife must be posi-
tioned within 3–8mm of the blade, as shown in
Figure 84.
The riving knife (see Figure 81) is a metal plate
that prevents the workpiece from pinching the
backside of the blade and causing kickback. It
also acts as a barrier behind the blade to shield
hands from being pulled into the blade if a kick-
back occurs while the operator is reaching behind
the blade. (Reaching behind the blade is a major
safety risk and should never be done.) Use the
riving knife for all operations.

The riving knife must be correctly installed, adjust-
ed, and aligned in order to provide the maximum
safety benefit.
The riving knife attaches to the mounting block as
shown in
Figure 82. Always firmly tighten the hex
nut when securing the riving knife in place.
