Sharpener Model 460, features
customized mixtures of 100%
diamond abrasives specially
designed to sharpen both straight-
edge and serrated knives. This
multipurpose manual sharpener
meets the needs of professionals,
chefs and serious cooks alike.
The Chef’sChoice Model 460 is a
two-stage sharpener designed to
ensure 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 double-
beveled 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 ser-
rated blades. Even new “factory-fresh”
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-than-new condition. The
cutting effectiveness of the serrations
depends almost entirely on the sharp-
ness 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...

MultiEdge

sharpener Model 460 is
“ambidextrous”-extremely easy
to use whether you are right-or left-
handed. 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, 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 center the blade left to right
in the slot. While continuing to keep
the blade centered in the slot, move
the blade smoothly back and forth in
the slot along the entire blade length.
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-and-forth 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.
