Chef's Choice Pronto Diamond Hone 463 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 suchthat by sharpening inboth 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 cleanyourknife beforesharpen-
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 formedin Stage1 ata nominal15degrees
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 staysharplonger.Always use thesharpener
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 sustainedcontact withboth of thetwo
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 aseffective 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
Congratulations!!
The Pronto®Model 463 designed to sharpen
Asian style blades is manufactured by
Chef’sChoice®, the world’s leader in cutting
edge technology. It is an exceedingly
fast manual sharpener that will create an
exceptionally effective cutting edge on your
Asian style cutlery. The cutting edge is finely
honed to extreme sharpness but retains
strong microscopic teeth that gives it a highly
effective bite for all your food prep needs and
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
Pronto®is to use and how well your Asian
knives will perform. Read and follow the
instructions carefully. Keep the sharpener
close at hand so that you can enjoy the
pleasure of sharp knives every day.
DESCRIPTION OF THE PRONTO®
You will appreciate that the soft touch
ergonomical 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.

of the blade aligned with the center line of the
slot as you sharpen.Apply about 3-4 pounds
downward pressure on the blade in Stage 2.
Hold the blade level,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 Pronto®”, making two to
three (2-3) pairs of strokes while maintaining
recommended downward pressure. Gener-
ally you should be able to resharpen several
times using only Stage 2. Listen to confirm
the sharpening disks are turning. Test edge
for sharpness and if necessary make four
(4) back and forth pairs of repeated strokes
in Stage 1 followed by two to three (2-3)
pairs in 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
The Pronto®which sharpens at a primary
angle of 15 degrees, can sharpen all double
faceted Asian blades such as the Santoku
which is traditionally sharpened at 15º.
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 versatile
Chef’sChoice®Electric Model 15XVand Model
1520 are designed to also sharpen all single
faceted Asian style knives.
CERAMIC KNIVES
The 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.

Mundial, Cuisinart, Kitchen Aid and many,

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.
