About serrated knives

Serrated knives are essentially saws with
teeth along the cutting edge. Depending
on the manufacturer and intended use,
the size, number and shape of the teeth
can vary widely. These teeth (serrations)
may either be ground into only one side
of the blade creating an asymmetrical
(off-center) edge; or may be ground into
both sides of the blade so that the teeth
are symmetrical (centered). The important
thing to remember is that, for household
use, 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 top and sides of the scallops between
the teeth, since in general, they are not
doing the cutting. The Chef’sChoice
Model 430 sharpener is designed to
sharpen teeth at the edge or point so that
the prominent teeth become razor-sharp
“micro knives.”

to use whether you are right-or left-hand­ed. Place the sharpener on a level surface
about waist high. If right-handed, position
the sharpener with the Chef’sChoice

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 knife 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 in slot. Lean the face of the
blade securely against the red 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 “sawing”
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-and-forth motion
until the blade is sharp.

Do not oversharpen. The number of
strokes required will depend on the size
and type of serrations and the condition
(dullness) of the teeth.

The Chef’sChoice

Hone

sharpener has been designed with

®

Manual Diamond

the optimal diamond abrasive to sharpen
your knives safely while producing an
extremely sharp edge. A coarser grit
would cause excessive wear and tear
of the serrations. The fine diamond grits
used in the Model 430 helps 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.

Sharpening for the first time

Knives with fine serrations and a
symmetrical edge (serrations on both
sides of the edge) may require only 10 full
strokes the first time you sharpen them.
Knives with larger thicker, off-center, or
very dull teeth may require up to 50 full
strokes. (A full stroke is one pull along the
entire cutting edge of the knife through
the sharpener together with the return
stroke, pushing the entire cutting edge of
the knife through the sharpener.)

Start with only 10 full strokes and
apply no downward pressure. Examine
teeth along blade for sharpness and wear.
Check your progress by periodically
testing the edge on food; e.g. tomatoes.

Resharpening

Knives can be resharpened using the
procedures described above. However,
resharpening will be faster and, in
general, require only about 10-20 full
strokes with care. 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
Manual Diamond Hone

Sharpener are

®

very fine, in time, serrations will be
reduced in size and the knife will perform
more like a sharp find edge blade. To
avoid excessive removal of metal on the

serrations, use little to no downward
pressure when sharpening and sharpen
just long enough to sharpen the points of
the teeth.

Instructions for Sharpening
Electric Knife Blades
(2 Reciprocating Blades)

1. Insure that the electric knife is
disconnected from the power source.

2. With the 2 reciprocating blades
installed in the normal manner in drive
unit proceed with sharpening.

3. Insert the knife (with blades in place)
into the sharpening slot and lean them
against the red roller guides.

4. Move the knife back and forth 10-20
times until a noticeable improvement
in the sharpness of the tips of the
serrations is achieved. With some very
dull knives more than 20 back and
forth cycles might be needed.

NOTE: Do Not apply any downward pressure on the knife

during sharpening.

5. It is important that the knife blades
remain in contact with the roller guides
during the entire sharpening process.
Make sure that at least one of the red
roller guides is always rotating as the
knife is moved back and forth.

6. Most of the electric knives are
equipped with 2 reciprocating blades
that interlock at the tip with a specially
designed rivet. This rivet may prevent
sharpening the very tip of the knife.
However, in most cases, that portion
of the blade does not play a very
important role in the cutting function.

7. After many sharpenings, the size of the
serrations will be reduced. However,
knife blades that may have become
useless because they were too dull
can be revitalized several times,

significantly extending their useful
lifetime and saving the cost of buying
replacement blades more often.

Testing for sharpness

Try slicing a tomato or other food before
you sharpen your knife. Then test the
knife periodically during sharpening until
you achieve the sharpness you desire.
Ideally, a well-sharpened knife should
slice cleanly through food without
excessive force and without crushing it.

Suggestions

If left-handed, turn the sharpener so the
Chef’sChoice

®

brand name faces away
from you. Hold the handle with your right
hand and the knife with your left and
follow the instructions above.

Never sharpen a knife that is not
completely clean. Small amounts of food,
fat or grease on the knife will coat the
abrasive surfaces and seriously reduce
their effectiveness.
