Sharpening
1. Hold the knife and the jig as illustrated. Make sure that you
press your thumb or palm against the jig so that the stop is always
in contact with the Universal Support. Move the knife back and
forth across the grinding wheel at a steady pace. Ensure that the
blade is in contact with the entire width of the grinding wheel.
When you reach the curved part of the blade, lift the knife handle
forward and upwards so that it has the same bevel as the rest of
the blade. Do not pull the handle towards you, this will give a taller
bevel on the tip than on the rest of the blade.
2. Grind until a burr forms along
the entire top of the blade. This
can be felt by using a finger to
lightly stroke the blade from the
back of the knife and down over
the edge.
Tip
Hold the knife so that the water flows evenly over the blade. The blade is then
in contact with the entire width of the grinding wheel, which is important for an
even bevel.
In good light, the burr will show
up as a pale line. When you
have a burr along the entire
blade, the first side is finished.
4. When the first side is sharpened, turn the jig upside-down while
the knife is still fixed in the jig and sharpen the other side. Now
the burr appears immediately as it has already appeared on the
underside and bends up. Sharpen as much as on the first side to
obtain a symmetrical edge. 5. The burr will be weakened
and more easily removed if you
grind the first side again with
very light pressure.
Tip Sharpening long knives can be facilitated if you remove the honing wheel.
