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.

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.

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
