Lift the tool and then move it
sideways during the sharpening.
Do not slide the tool. Press with
your thumb close to the edge.
Turn the jig around and shape
the other side. Apply forward
pressure on the handle side.
Apply forward pressure on the
handle side to compensate for
the force of the wheel against
the tool.
Shaping
When the desired shape is achieved, check that the protrusion
has not decreased during the shaping. If so, re-position the tool
to the right protrusion and then complete the shaping. By doing
so, you ensure that you will exactly replicate the edge geometry
at future sharpenings.
Activate the grindstone dur-
ing the grinding process with
the coarse side of the Stone
Grader SP-650.
Grind until the bevels are
symmetrical. If necessary
grind the first side again.
When shaping a wide chisel, you can increase the efficiency
of the stone by grinding half the width at a time. The grinding
pressure will increase, which makes the stone grind faster.
Complete the sharpening with
the entire bevel on the wheel.
Lift the tool to move it sideways.
