Knife Sharpener

2 Stage

460

INSTRUCTIONS

For Use on Both Straight Edge
and Serrated Knives

The professional Chef’sChoice
Diamond Hone® MultiEdge
Sharpener Model 460, features
customized mixtures of 100%
diamond abrasives specially
designed to sharpen both straight­edge and serrated knives. This
multipurpose manual sharpener
meets the needs of professionals,
chefs and serious cooks alike.

The Chef’sChoice Model 460 is a
2 Stage sharpener, incorporating
a pair of contoured roller guides to
ensure precise and consistent angle
control - stroke after stroke -as the
knife is presented to the diamond
sharpening elements. Both sides of
the edge are simultaneously shaped
and sharpened. This construction
ensures that the edges are well
formed and very sharp every time.

The abrasives consist of selected
100% single-diamond crystals
embedded on unique interdigitating
steel support plates. The Model
460 consistently outperforms
conventional sharpeners that use

less efficient abrasives and lack any

control of the sharpening angle.
Diamonds, the hardest known
material, are extremely durable.

Straight-edge knives sharpened
on the Model 460 will be “shaving
sharp” with a “bite” that helps them
cut effortlessly through tomatoes,
other vegetables and fruits. It makes
cutting and slicing a pleasure and
removes the drudgery of working
with dull knives. Straight-edge knives
are sharpened first with diamonds in
Stage 1 and then at a different angle
with still finer diamond mixtures
in Stage 2. This creates a double­beveled longer-lasting arch-shaped
edge that is much stronger than
conventional “v-shaped” or hollow
ground edges. This unique arch
structure ensures a sharper edge
that will stay sharp longer.

Serrated knives sharpen quickly in
Model 460 using only the second
sharpening stage. The special
diamonds in that stage create
razor-sharp “micro-blades” along the
dominant teeth, enhancing the cutting
action and reducing the sawing and
tearing action otherwise typical of
serrated blades. Even new “factory­fresh” serrated knives frequently have
poorly formed, dull saw teeth that can
benefit from sharpening and shaping
in the Model 460. Serrated knives
become dull because their teeth bend
and distort during use. The Model
460 restores dull teeth to better-than­new condition. The cutting effective­ness of the serrations depends
almost entirely on the sharpness of
the points (edges) of the teeth. It is not
necessary to sharpen the sides and
bottoms of the scallops between the
teeth, since in general, they are not
doing the cutting. The Chef’sChoice
Model 460 sharpener is designed to
sharpen teeth at the edge or point
so that the prominent teeth become
razor-sharp “micro-blades.”

®

Serrated knives sharpened with
the Chef’sChoice® Model 460 glide
smoothly through food and cut
cleanly with less effort. There is less
tearing or mutilating of all types of
food including meat, poultry,
vegetables and bread. The face of a
cut vegetable or fruit is smoother and
more appetizing. The sharpened
serrated knife is easier to control
allowing you to make thinner slices
and to manipulate the blade easily
for garnishing.

The “micro-blades” created by the
Model 460 along the prominent teeth
of serrated knives are unique in that
they give the knife some of the
qualities of a straight-edge blade
while retaining the sawing action of a
serrated edge. This combination
creates the ultimate serrated edge.

Before you begin...

The Chef’sChoice® Diamond Hone®
MultiEdge
is “ambidextrous”-extremely easy
to use whether you are right-or left­handed. Stages 1 and 2 are marked
on both sides of the sharpener for
your convenience.

Place the sharpener on a level surface
about waist high. If right-handed,
arrange the sharpener with the
Chef’sChoice® brand name facing you.
Hold the handle with your left hand

making certain that your left index finger

and thumb remain safely behind the
partitioning wall where the handle
attaches to the sharpening stages.
(If left-handed, see Suggestions.)

Caution: Keep all fingers clear of the
blade at all times.

General sharpening instructions

Make certain the blade is clean - free
of all food, fat and grease - then
proceed as follows:

Holding the knife in the right hand,
place the blade into the “v-shaped”
slot and lean the blade securely
against the conical roller guides.
While continuing to keep the blade
in contact with the rollers, move the
blade smoothly back and forth in the
slot along the entire blade length.
Make sure one or both rollers move
with each back-and-forth stroke to
ensure that the blade is in good
contact with the rollers. It is not
necessary to lift the blade after each
stroke. Apply little or no downward
pressure on the blade. The light
sound you hear as the blade moves
across the 100% diamond abrasives
tells you the diamonds are doing the
work for you! Continue this back-and­forth motion until the blade is sharp.

The Chef’sChoice® Diamond Hone®
manual sharpener has been designed
with the optimal diamond abrasive
mixture to sharpen your knives
safely while producing an extremely
sharp edge. Coarser grits would
cause excessive wear and tear of the

serrations. The fine diamond grits

used in the Model 460 help extend

the life of your knives. The first time

you sharpen a knife may take a little
longer, but resharpening will be fast
and safe.

Instructions for use

Straight-edge Blades

(Use Stage 1 and then Stage 2)

Generally 25 back-and-forth strokes
in Stage 1 are sufficient to develop

a sharp edge. Hold the face of the
blade firmly against the contoured
rollers. One or both rollers will turn
as the knife is pulled or pushed back

and forth through the slots indicat­ing proper sharpening and good
angle control. Maintain contact with

the abrasive but put no additional
downward pressure on the knife
while sharpening.

If the knife is very dull it may take
more back-and-forth strokes, per­haps up to 50 or so through Stage
1 to develop a sharp edge. Do not
proceed to Stage 2 until the edge is
very sharp. It should, for example, be
sharp enough to cut easily through
the skin of a tomato.

Now, make 10 back-and-forth
strokes in Stage 2 to hone the edge

to shaving sharpness. Apply no

downward pressure on the blade.
Too much pressure can reduce

the ultimate edge sharpness. Test
sharpness by cutting a tomato, or by
cutting paper*.

Serrated Knives

Serrated blades should be sharpened
in Stage 2. Generally, 25 back­and-forth strokes in Stage 2 will be
sufficient. Keep the blade in contact
with the roller guides but apply no

added downward pressure on the
blade. Check sharpness by cutting

a tomato, vegetable or fruit. Note the
improved smoothness of the cut after
the blade has been sharpened. (The
paper cutting test is inappropriate for
a serrated knife.)

If the blade needs further sharpening,

continue back-and-forth strokes in
Stage 2 until the desired sharpness

achieved. Sharpening in Stage 1 can

remove excess metal and shorten
the life of the serrated blade,
consequently use that stage only if
the teeth are extremely dull or bent.

* To test periodically for sharpness, hold a sheet
of paper by its edge and carefully slice through it,
making sure you cut a short but safe distance
from your fingers. A sharp blade will cut smoothly
without tearing the paper.

Resharpening

Knives can be resharpened using
the procedures described above.
However, resharpening will be much

faster and, in general, require only
about 25 full back-and-forth strokes.
You will be able to resharpen your

serrated knives many times before
the serrations become notice­ably worn. Although the diamond
abrasives used in the Chef’sChoice

®

Diamond Hone® Manual 460 are very
fine, in time, serrations will be reduced
in size. However, a serrated knife that
may have become useless because

it was too dull will be revitalized by
the Chef’sChoice® Diamond Hone

Manual sharpener

Suggestions

• If left-handed, turn the sharpener
around, hold the handle with your
right hand and the knife with your

left, and follow sharpening and
honing instructions above.

• With thick straight edge blades,

it is sometimes useful after

following the instructions for Stage
2, to turn the sharpener around,
holding the handle with the other
hand, and carefully repeat the
sharpening process in Stage 2 with
a few back-and-forth strokes from

the other side. Be sure to maintain
blade contact with the rollers.

• Straight edge knives that are

extremely dull may require many
strokes in Stage 1. Stop periodically
and check the blade for sharpness
by carefully cutting paper.
Then hone the knife in Stage 2.

Electric Knives

It is possible to sharpen the serrated
blades of electric knives that have
become dull. First disassemble the
two blades used in most electric
knives and sharpen individually as
described above.

Maintenance

• The exterior can be cleaned with
a damp, soft cloth.

• No oils, water or other lubricat­ing liquids are necessary with this
sharpener.

• Not for scissors.
