Rotating or replacing blades
Both the upper and lower blades have four cutting
edges on each side (the front and back). When the
cutting edge becomes dull, rotate both the upper and
the lower blades 90° to expose new cutting edges.
When all eight edges are dull on both the upper and
lower blades, replace both blades with new ones. Each
time blades are rotated or replaced, proceed as follows.
