Chef's Choice Commercial Pronto Diamond Hone 465 User manual

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 ribbed handle
further reduces the opportunity for slippage
while sharpening.
USING THE COMMERCIAL 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 parti-
tion 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 intofirm sustained contact withboth
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 theslot 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 findthat only about 10 orless back
and forth stroke pairs in Stage 1 (with recom-
mended 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 2-3 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
length of the blade aligned with the center
line of the slot as you sharpen. Apply about
4-5 pounds downward force in Stage 1 and
Congratulations!!

especially for fibrous materials. The edge is
surprisingly durable yet can be resharpened
quickly whenever necessary.
You will be pleased to see how easy the
Commercial Pronto®is to use and how well
your knives perform. Read and follow the
instructions carefully.Keep the sharpenerclose

efficiency of sharp knives every day.
DESCRIPTION OF
THE COMMERCIAL PRONTO®
You will appreciate that the non-slip ergo-
nomical handle of the Pronto®is extremely
comfortable providing a secure grip. There
are two slots, the first (#1) uses fine diamond
abrasives to create and hone a sharp primary
edge and a second slot (#2) where that edge
is ultrahoned at a slightly larger angle with
micron size diamonds to its final sharpness.

a little less – about 3-4 pounds pressure on
the blade in Stage 2. Make smooth consistent
strokes while maintaining recommended
downward pressure and make certain the
disks are turning.
RESHARPENING THE KNIFE EDGE
Follow the procedure for Stage 2 described
above for “Using the Commercial Pronto®”,
making two to three (2-3) pairs of strokes
while maintaining recommended downward
pressure. Listen to confirm the sharpening
disks are turning.Test edge for sharpness and
if necessary make four (4) back and forth pairs
of strokes in Stage 1 followed by two to three
(2-3) pairs in Stage 2.
Generally you should be able to resharpen
several times using only Stage 2.
SERRATED BLADES
Serrated blades can be sharpened in Stage
2. Center the blade in the slot of Stage 2 and
make five (5) forward and back stroke pairs.
Examine the edge and if necessary make
another 5 full strokes. Examine blade. If the
blade to be sharpened is very dull, first make
two full strokes (forward and back pairs)
in Stage 1 and then make five (5) paired
strokes in Stage 2. Because of its nature, a
serrated knife will never appear as sharp or
cut as smoothly as a straight edged blade.
Caution: Do not make many strokes in Stage
1, which can quickly remove metal from a
serrated edge.
ASIAN BLADES
ThePronto®which sharpens at a primary angle
of 20 degrees, can sharpen double faceted
Asian blades such as the Santoku which is
traditionally sharpened at 15º. However, for
optimum results we recommend the Com-
mercial 2100 with optional 15° sharpening
module, or for lighter use, a 15º sharpener
such as the Chef’sChoice®Electric Models
15XV or 1520 as the preferred choice for all
Asian style blades.
Do not sharpen in the Pronto®any single
sided, single faceted Asian Kataba knives,
such as the traditional sashimi styled blade
that is commonly used to prepare ultra thin
sashimi. The Pronto®sharpens simultane-
ously both sides of the cutting edge while the
sashimi knives are designed to be sharpened
only on one side of the blade. The previously
mentioned Chef’sChoice electric sharpeners
will also correctly sharpen these single
sided knives.
CERAMIC KNIVES
The Commercial Pronto®is not recommended
for ceramic knives.
SCISSORS
Do not attempt to use the Pronto®to sharpen
scissors. EdgeCraft does manufacture both
electric and manual scissor sharpeners.
BRANDS OF KNIVES
The Commercial Pronto®will put an
excellent edge on all of conventional metal
Euro/American and Santoku style knives
regardless of brands, including Henckels,
Wüsthof, Sabatier, Lamson and Goodnow,
Global, Russell Harrington, Chef’sChoice,
Messermeisser, Forshner, Mundial,Cuisinart,
Kitchen Aid, Shun and many, many more.
TEST FOR SHARPNESS
To test for sharpness and cutting ability of your
knife, hold a sheet of paper vertically by its
upper edge and carefully cut down through
the sheet a small (but safe) distance from your
fingers.A sharp edge (on a straight edge blade)
will cut smoothly without tearing the paper.
Alternatively try cutting a tomato.The knife
should penetrate the skin of the tomato and
cut through it on the first pull without applying
significant force to the knife.
