In each, the first and second stage, both
sides of the edge are sharpened simultane-
ously by two precision diamond coated conical
honing disks. The orientation of the disks is
such that by sharpening in both stages the
entire length of the edge is sharpened.
Small rubber feet secure the Pronto

to
any dry clean surface. The soft touch handle
further reduces the opportunity for slippage
while sharpening.
USING PRONTO
®
Note: Always clean your knife before sharpen-
ing in the Pronto
®
!
You will find that the Pronto
®
can create and
maintain an exceedingly sharp and effective
edge on all your conventional fine edge and
serrated cutlery. The primary edge facets
are each formed in Stage 1 at a nominal 20
degrees which results in a total primary edge
of 40 degrees. Stage 2 creates a second bevel
at a slightly larger angle leaving a strong
double beveled edge structure that will stay
sharp longer.
Always use the sharpener with the stage
numbers 1 and 2, facing you.
Safety: Keep your fingers clear of the
blade edge at all times. Hold the handle with
your left hand making certain that all your
fingers and thumb remain safely behind the
partition wall where the handle attaches to
the sharpening stage.
STAGE 1
To sharpen, hold the sharpener on the table
with your left hand. Insert the knife blade into
the slot of Stage 1. Press down to bring the
knife edge into firm sustained contact with
both of the two internal diamond coated disks
and slide the blade back and forth in a sawing-
like motion. For optimum results center the
blade left to right in the slot and avoid rubbing
against the walls of the slot. Apply a downward
force of about 4-5* pounds as you move the
blade. Listen carefully to the disks to insure
they are rotating when you move the blade.
Sharpening will not be as effective if you press
too lightly while sharpening.
If your knife, before sharpening, is not very
dull you may find that only about 10 or less
back and forth stroke pairs in Stage 1 (with
recommended downward pressure) will be
sufficient to put a keen edge on the blade.
However, if the knife starts out very dull you
may find that 20 or more back and forth paired
strokes will be needed the first time as you
reshape and sharpen the old edge. Before
leaving Stage 1 check the edge for sharp-
ness by slicing a piece of paper. It should cut
paper readily with only a slight roughness to
the cutting action.
* 4 to 5 pounds is about the weight of a 2 inch thick
telephone book
STAGE 2
If the knife is correctly sharpened in Stage 1
only 2-3 back and forth stroke pairs in Stage
2 will complete the small second bevel and
the edge will be very sharp and effective. It
should cut paper smoothly allowing you to
make straight or curved cuts easily.
For optimum results center the blade
(left and right) within the slot and keep the
