8. Smoothing the convex surface with a 9 micron disc
A. Once you have completed your sharpening on the
15 micron disc, set the Hira-To® to the neutral
position, remove the 15 micron disc, and replace it
with a 9.
Note: For true left hand scissors turn motor on counter-clockwise.
B. Set the Hira-To® speed at 8 and turn the machine on so the
machine is spinning clockwise.
C. Lay the blade on the disc and gently rotate the
blade back and forth in the fixture. Be careful to
lighten pressure on the tip and the throat of the
blade. Do your best to follow the gentle curve
of the cutting edge.
D. After working your blade on the 9 micron disc,
lift the blade off the disc, rotate the fixture, and
check the cosmetics (appearance of the convex
front surface).
*If the scratches are still too deep from the 15
micron disc, continue to work the blade on the
disc until you smooth the convexed surface of the
blade. (Note: We do this step to smooth over the
scratches from the 15 micron disc.)
