Congratulations on your selection of
the Chef’sChoice®Commercial Knife
Sharpener Model 2000!
You will find this method of sharpening puts an exceptionally sharp and durable edge on all
of your knives. It is backed by EdgeCraft—World Leader in Cutting Edge Technology®.
The Chef‘sChoice®Commercial Diamond Hone®Knife Sharpener Model 2000
incorporates advanced diamond abrasive and honing technology to produce the sharpest
and most durable edges of any sharpener available today. With it you can develop a
shaving-sharp edge on all your knives. Once your knives have been sharpened on the
Model 2000, resharpening takes less than 1 minute.
Consequently, if the Model 2000 is conveniently located in your work area, you can
resharpen so rapidly that you need not rely on the sharpening steel to tune up the edge.
UNPACKING AND PREPARING FOR OPERATION
The Model 2000 has a motor-drive section and a detachable Sharpening Module that is
packed and shipped disassembled (see Figure 1).
To assemble the Model 2000, insert the Sharpening Module into the guide rails of the
motor section, (Figure 2) and slide the module toward the motor housing until it locks in
place. If the sections do not snap together easily & quickly, follow the instructions in the
“Inserting” section, (Page 8) of this manual.

DESCRIPTION - MODEL 2000 SHARPENER
The Model 2000 sharpener uses a novel two-stage sharpening and honing process, where
the knife is first sharpened with a pair of conical diamond-coated wheels and then honed
with a pair of patented conical honing disks incorporating ultrafine abrasive particles. This
creates a unique edge geometry that gives the edge extraordinary “bite” and sharpness
and ensures it will stay sharp much longer than conventionally sharpened knives. The
Sharpening Module, incorporating both the sharpening and honing stages, is a self-con-
tained unit that can be removed for washing and sanitizing in a dishwasher or at the sink. It
can be removed simply by depressing the release button (Figure 2) and sliding the module
off the motor-drive section.
A powerful 150 watt motor operating at 1700 RPM is enclosed in the motor housing.
Splined drive couplings attached to the shafts of the motor drive and the Sharpening
Module permit their rapid engagement or disengagement.
In both the sharpening and honing stages, the edge must be sharpened on alternate
strokes in the right and left slots (see Figure 3). Precise “Blade Guides” position and align
the knife at the correct angle while plastic hold-down springs stabilize and secure the
blade as it is pulled through each slot and makes contact with the abrasive wheels. The
downward movement of the blade in each of the slots is limited and controlled by an Edge
Stop Plate (Figure 3), made of a high-density polymer that serves both as a stop and as
a micro-guide “slot” for the edge, without damaging the sharp edge being formed. There
are Edge Stop Plates at the front and rear of the sharpening and honing stages. For best
results, the knife edge should only just touch or lightly rest on the front Edge Stop Plate.
Excessive downward pressure is unnecessary and will result in excessive cutting of the
Edge Stop Plate. The edge need not rest on the rear Stop Plate for the entire sharpening
and honing stroke.

and the plastic spring until edge rests lightly on Edge

Knife Blade Guides

The sharpening and honing disks are spring-loaded on their drive shaft to provide an
optimum sharpening pressure that ensures rapid yet uniform sharpening along the length
of the edge and minimizes the potential for gouging the edge.
The knife is first sharpened in Stage 1 with alternate pulls on each stroke in the right and
left slots. Depending on the condition of the edge, it may be necessary to make only 2-3
alternating pairs of pulls in each slot. With a very dull or heavily steeled edge, it may be
necessary to make as many as 10 alternating pairs of pulls before moving to Stage 2. In
any event, whenever sharpening in Stage 1, proceed until a distinct and uniform burr is
created on the edge along the entire blade length on each successive pull through the right
and left slots. A burr (as shown in Figure 4) is a distorted and bent over edge created by
the sharpening process. Its presence is a confirmation that the sharpening in Stage 1 is
complete and the knife is ready to be honed in Stage 2.
It is important to know how to feel for the burr. It is relatively easy to feel by moving one or
more fingers across and away from (not along or into) the edge. One convenient method
of doing this is shown in Figure 5. Grip the blade as shown. Put the index finger and/or the
middle finger in contact with the face of the blade and move it/them forward across and
away from the edge. The burr will be detected only along the side opposite from the one
last sharpened (for example, if the last pull was through the right slot of Stage 1, the burr
will appear on the right side of the knife). There will be no burr on the opposite side of the
knife edge until the knife is pulled through the other slot. Pull through other slot and make
certain burr is created there. Caution: To avoid any danger of being cut, do not move
fingers along the length of or into the blade edge.

After developing a burr in Stage 1, the knife edge is honed in Stage 2. Using the same pro-
cedure as in Stage 1, the knife is pulled through, alternating in the left and right slots. The
angle guides in this stage are set at a slightly larger angle than Stage 1, thus developing
double-beveled facets along each side of the edge. The facet formed in this stage is very
narrow and might best be described as a micro-bevel immediately adjacent to the edge
itself. Normally only three pairs of alternating pulls in Stage 2 are sufficient. You will now
find no trace of a burr and the edge will be extremely sharp.
Caution: The resulting edge is likely to be much sharper than you are accustomed to
and must be handled with great care to avoid personal injury.
The sharpening and honing disks have a normal life of about 3000 resharpenings. You will
observe a 2 to 3 fold decrease in the aggressiveness of the diamond wheels during this time.
Replacement sharpening modules are available from your distributor or the factory.
OPERATING PROCEDURE
Sharpening - Stage 1
1. Turn the sharpener on. CLEAN THE KNIFE BEFORE SHARPENING. Accumulation of fat or
grease on sharpening disk will reduce its effectiveness.
2. Stand facing the front of the sharpener (facing the on/off switch side). Place the knife in
Stage 1 in the slot between the plastic spring guide and the knife Blade Guide as shown in
Figure 7, making sure the face of the knife blade is resting flat against the Blade Guide. You
can start in either the right or left slot, but always alternate slots after each pull.
3. Move the blade downward in the slot while slowly pulling it toward you until it contacts the
rotating diamond disk. Make sure as you pull the knife down and forward through the slot
that it is fully inserted and its edge rests lightly on the front Edge Stop Plate (as seen in
Figure 6). Apply only just enough downward pressure to make contact with the front Stop
Plate. Additional pressure is unnecessary and counterproductive. Do not be concerned about
resting the knife edge on the Edge Stop Plate; it was designed so that it will not damage the
knife’s edge.

4. Repeat Step 3 on each side of Stage 1, alternating in the right and left slots until you can
feel a uniform burr along the entire length of the knife.
5. Each pull should take about 4 to 6 seconds for an 8” knife. As you approach the tip of the
knife, lift the handle slightly to keep that part of the edge parallel to the table. Continue to
rest the edge lightly on the front Edge Stop Plate.
6. Normally 2-3 pairs of alternating pulls in Stage 1 will be sufficient to create a burr, unless
the knife is very dull or has been sharpened with a traditional steel since the last sharpen-
ing with the Model 2000. In the latter case, 5 or more pairs of alternating pulls in Stage 1
may be required to reform the edge facets and develop a burr. If you have difficulty creating
a burr, pull the blade through the slots at a slower rate. Going slower is more helpful than
many pulls.
7. When you confirm that a burr is formed along the entire edge length on each successive
pull, move to Stage 2.
Honing-Stage 2
1. MAKE CERTAIN THE KNIFE IS FREE OF FOOD, FAT OR OIL. Facing the front of the sharpener,
place the knife in one slot of Stage 2 as shown in Figure 7 with the face of the knife blade
lying flat against the Blade Guide.
2. Move the knife into the slot downward and forward until it engages the honing disk.
The knife edge should be gently seated on the Edge Stop Plate as it is pulled toward you.
3. Repeat Step 2 on each side of Stage 2, alternating in the right and left slots for
approximately 3 pulls on each side.
4. Each pull should take about 4 to 8 seconds for an 8” knife. Again, as in Stage 1, slightly lift
the handle as you approach the tip area, but continue to keep the edge in light contact with
the Edge Stop Plate.
5. Generally 3 alternating pairs of pulls are sufficient. Test the edge for sharpness by cutting a
piece of paper or slicing a tomato and, if it is less than razor sharp, pull several more times
in each slot of Stage 2. If the knife is not ultra-sharp, return to Stage 1 and develop a burr
before repeating the honing sequence.

right slots to create the final bevel. Knife edge rests

RESHARPENING
Normally you can resharpen rapidly with 3-5 pairs of alternating pulls through Stage 2 only.
You will be able to resharpen 3-5 times just in Stage 2 before having to sharpen again in
Stage 1. You may find it easier and faster to sharpen using Stage 2 for all resharpening
rather than using a sharpening steel for periodic touch-up of the edge. Periodically,
however, you will find it necessary to resharpen first in Stage 1 followed by Stage 2 in
order to develop the shaving-sharp edge that should be created in Stage 2.
If a traditional sharpening steel is used repeatedly to tune up the edge between
resharpenings on the Chef’sChoice®Model 2000, you will have to resharpen first in
Stage 1, following the normal sharpening procedure and then hone in Stage 2. In this case
it will take 3 or more alternating pairs of pulls in Stage 1 to achieve a uniform burr before
proceeding to Stage 2.
In view of this, if you wish to improve productivity and reduce sharpening time, you should
avoid using the traditional sharpening steel and rely on Stage 2 for fast resharpening.
Make sure the knife is free of food, fat or oil before resharpening in Stage 2.
SERRATED KNIVES
While the Chef’sChoice®Model 2000 is designed primarily for non-serrated knives, it will
significantly improve the performance of serrated knives by honing the tips of the
serrations. Two or three pairs of pulls, alternating through the left and right slots of Stage 2
(Honing) should be sufficient.
Caution: Do not use Stage 1 on serrated knives!
REMOVING, CLEANING AND INSERTING THE SHARPENING MODULE
When there is evidence of grease, fat, or food on any of the sharpening wheels or on the
Sharpening Module where it cannot be readily removed, it is time to wash the module
as described in the following section. We recommend knives always be cleaned before
sharpening – at a minimum, wipe them down with a cloth in order to reduce the need for
frequent cleaning of the Sharpening Module.
To remove the Sharpening Module, first make sure the motor switch is in the “OFF”
position. Then press the release button while pulling the Sharpening Module away from
the motor housing (see Figure 8.) The Sharpening Module should remove easily.

CLEANING THE SHARPENING MODULE
This appliance is not to be cleaned with a water jet. (NEVER immerse the motor-drive
section in water or spray it with water. When soiled, unplug it and wipe with a damp cloth).
The Sharpening Module should be removed as described. It then can be cleaned by either
of the following methods:
A. Washing by hand:
1. Spray the wheels in each stage with liquid dishwasher detergent.
2. Allow to soak for a few minutes in a pan, bucket or sink to loosen any attached food, etc.
3. Rinse or spray under a strong stream of warm water.
4. Drain on paper towels. Blow dry if clean pressurized air is available.
5. CAUTION... do not towel dry; you may damage the plastic hold-down spring.
6. If diamond wheels are not shiny they may have grease on them. Put sharpening module
through dishwasher.
B. Dishwasher:
1. Spray the wheels in each stage with liquid dishwasher detergent.
2. Put in dishwasher on normal wash cycle.
3. Allow unit to dry in the dishwasher, preferably in a position remote from the heaters.
Periodically remove any metal dust that has collected in the two collection cavities
located below the sharpening and honing stages in the base of the sharpener (under the
Sharpening Module.) With the Sharpening Module removed, simply invert the motor
housing and shake the dust loose. Otherwise remove with a damp sponge. Do not use a
water spray to remove the loose dirt.
INSERTING SHARPENING MODULE
To reinsert the Sharpening Module into the main motor housing, insert the shaft coupling
end of the Sharpening Module into the guide rails at the right end of the sharpener. Then
gently push the Sharpening Module (as in Figure 2) toward the motor housing until it locks
in place. If it resists snapping into the locked position: (1) Pull the module away from the
motor shaft until it fully disengages; (2) turn the motor switch on briefly; (3) then turn it off;
(4) while the motor is coasting to a stop, push the Sharpening Module into place. It will then
automatically snap into position when the spline coupling becomes properly aligned.
CHANGING THE EDGE STOP PLATES
The Edge Stop Plates, especially the pair in front of the sharpening and honing stages, will
in time develop small cuts in the surface where the knife rests during sharpening. This
is normal but the depth of the cuts can be minimized by applying just enough downward
pressure to keep the edge in contact with the Plate. When these cuts approach 1/8” deep,
the Edge Stop Plates should be turned over or replaced. The Plates generally can be
removed simply with a pair of needle nose pliers or by prying them up and out gently with
a pointed tool. They can be inverted, when worn, to expose a fresh edge for contact with
the blade. With experience you will find that little or no pressure is necessary against these
plates and that they will last a long time. Replacement Stop Plates are available directly
from your distributor or from EdgeCraft (1-800-342-3255).

DRESSING THE STAGE 2 HONING WHEELS
If the Stage 2 honing wheels appear to be “glazing over” due to grease or other reasons,
or if you believe these wheels are less aggressive, you can clean them with the diamond
dresser supplied with your Model 2000 sharpener. This will restore the wheels to “like
new” condition. To dress the wheels, turn on the sharpener and insert and pull through
the dressing plate as shown in Figure 9. Insert the dresser between the plastic spring
and against the knife guide - just as you would insert a short knife for sharpening -
to make contact with the honing wheel and pull dresser plate through like a knife, pull
twice through the right and left slots as shown in Figure 9. Pull through in 2-3 seconds.
Remove plate when the process is completed.
HOW TO GET THE MOST OUT OF YOUR
Chef’sChoice®Model 2000
A. There is no maintenance required other than to clean the Sharpening Module periodically by
putting it in the sink or dishwasher. It is unnecessary to clean this module simply because
the honing wheels darken - that is normal. The wheels are self cleaning (through mild
ablation) unless they become covered with fat and grease. The need for cleaning can be
minimized by wiping your knives before and after sharpening as described in this manual.
Do not immerse the motor-drive unit in water. Clean it only with a damp cloth. Periodically
shake out the metal dust under the sharpening wheel as described under “cleaning...”
B. We suggest you locate the Model 2000 in a convenient place in your work area for
rapid resharpening. A few quick passes through Stage 2 will restore your knife edge to
razor sharpness.
C. Heavy cleavers (such as the ones made in Germany, France, etc.) can be sharpened on the
Model 2000. However, because most of these cleavers are manufactured with an extremely
blunt edge, it will require many pulls through Stage 1 to create the first bevel. Once
sharpened, however, the cleaver will resharpen rapidly. Asian cleavers are thinner and
sharpen quickly on the Model 2000.

11
D. Resharpen the knife in Stage 1 only when you cannot achieve satisfactory sharpness with a
few pulls through Stage 2.
E. This sharpener is supplied with an abbreviated set of instructions printed on an adhesive
backed plastic label. If you wish to keep these handy, remove backing and adhere to the top
surface of the motor housing. Replacement labels are available from EdgeCraft.
F. Replacement parts can be ordered from your local distributor or from the factory.
For customer service or assistance call 1-800-342-3255.
SERVICE
In the event post-warranty service is needed, return your sharpener to the EdgeCraft
factory where the cost of repair can be estimated before the repair is undertaken.
Please include on a separate sheet inside the box: your return address, daytime telephone
number and a brief description of the problem or damage to the sharpener. Retain a
shipping receipt as protection against loss in shipment.
