Single Blade Grinding (also know as “Relief
Grinding” or “Back Grinding”)
Stone
Toro recommends a 30_ relief angle on each reel blade.
The angle itself is not critical. You can put as little or as
much angle on the blade as you think is proper. A larger
angle will take off more steel and the reel will have to be
replaced sooner. With a smaller angle, you may have to
grind the reel more often.

To prevent possible personal injury, always
wear a face shield or safety glasses when
grinding or sharpening is being done.
Sequence for a 5 Blade Reel
START
END
It is a good idea to follow a blade grinding sequence dur-
ing the process so that the reel ends up as close to a cyl-
inder shape as possible. This will reduce the amount of
backlapping needed after grinding is completed.
1 – 2 – 3 – 4 – 5 – 1
2 – 3 – 4 – 5 – 1 – 2
3 – 4 – 5 – 1 – 2 – 3
4
– 5 – 1 – 2 – 3 – 4
The numbers shown in the illustration indicate one ex-
ample of the sequence that may be used. Remember
that a final grind in a spin grinder, or some backlapping
will get the reel into a true cylindrical shape.
5 – 1 – 2 – 3 – 4 – 5
. . . and so on until finished.
Goal: Approx. 30_ back angle and a land area.
It will normally take several passes across each reel
blade to renew the sharp edge and remove the taper
from the reel. This example may have required 4 or 5
passes and then was completed with a backlapping job
to create the land area. NOTE: It is acceptable practice
to grind in both directions across the blades.
