Pronto, Diamond hone, Knife sharpener for asian knives model 463

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 15 degrees 
which results in a total primary edge of 30 
degrees (15° on each side). 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.
FINE EDGE KNIVES
STAGE 1
To sharpen, hold the sharpener on the table 
with your left hand. Insert the knife blade into 
the slot of Stage 1. Hold the blade level with 
the table, 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 both 
disks 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 sharpness 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 2-5 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 length
