The riving knife works in the same manner as the spread-
er on the blade guard assembly. It is a metal plate that	D`e`dld(dd	?\`^_k;`]]\i\eZ\
prevents the newly cut workpiece from pinching the back-	DXo`dld,dd
side of the blade and causing kickback.
The key difference between the spreader and the riving
knife is that the riving knife mounts below the blade's			I`m`e^
highest point of rotation, as shown in =`^li\+0.
