6. Bringing up an edge with a 30 micron disc
A.
Start the sharpening process with a 30 micron
disc. Set the Hira-To® to the neutral position,
install the 30 micron disc.
Note: For true left hand scissors turn motor on counter-clockwise.
B.
Set the Hira-To® speed to 5 (50%) and turn the machine on so
the disc is spinning clockwise.
B.
Lay the blade on the disc and gently rotate
the blade back and forth in the fixture while
watching for a burr to come up.
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.
C.
Once you see that your burr has come up, lift
the blade off the disc, rotate the fixture, check
the cosmetics (dead spots, appearance of
the convex front surface, etc.), and feel for a
burr. *If the blade needs more work or if you
cannot feel a burr, continue to work the blade
on the disc until you achieve a satisfactory
edge.
