DESCRIPTION OF THE CHEF’SCHOICE HYBRID® DIAMOND HONE
KNIFE SHARPENER MODEL 250
This advanced Hybrid® Diamond Hone Sharpener has two motor driven sharpening Stages
1 and 2, followed by a single manual honing.
In Stage 1, motor-driven, highly eective diamond abrasive disks remove the dull edge
and create a sharp fully faceted edge at the conventional 20 degrees on each side of
the blade. In Stage 2 similar technology is used with finer diamond abrasives at a slightly
larger angle to create a small second bevel along the edge. This two step sharpening and
honing process leaves a stronger – arch shaped profile along the edge for greater strength
and durability. In Stage 3 the edge is lightly polished to create a razor sharp Trizor edge of
increased perfection, sharpness and durability.
In Stage 1 there are two knife-guiding slots. These are referred to as the left and right
slots of Stage 1. Likewise in Stage 2 there are two guiding slots, left and right that sharpen
alternately the right and left side of the blade’s edge. Stage 3 has only one guiding
slot that centers the blade in a manner so that both sides of the edge are honed
simultaneously. When sharpening in Stages 1 and 2, always follow an alternating pattern
of sharpening in the right and left slots. This pattern insures that both sides (facets) of the
edge are sharpened alike for better control of the cutting action of blade.
This three stage design provides the ultimate in versatility of the knife edge so that you
can tailor the edge geometry to your cutting needs. You will find that the Model 250 gives
you a very sharp edge and one that remains significant bite for some of the more dicult
cutting tasks.
USING THE MODEL 250 SHARPENER
Note: Always clean your knife before sharpening in the Hybrid ®! For your safety, keep your
fingers clear of the blade edge at all times.
You will find that the Hybrid® can create and maintain a very sharp and eective edge on
all your conventional fine edge and serrated cutlery. The primary edge facets are each
formed in Stage 1 at a nominal 20 degrees on each side of the edge, which results in a
total primary edge of 40 degrees. Stages 2 and 3 create a second and third bevel at
slightly larger angles leaving a strong triple beveled edge structure. Always use the
sharpener with the stage numbers 1, 2 and 3 facing you.

STAGE 1
To sharpen, place the sharpener on the table gripping it securely with your left hand. Push
on the power switch. Insert the knife blade, (Figure 1) near its handle, into the far left slot
of Stage #1 and allow the left face of the blade to rest on the left face of the slot as you
pull the knife toward you. The knife edge should be in sustained moving contact with the
internal diamond abrasive coated disk. Only light downward force will be necessary as
you pull the blade toward you. Listen carefully to insure your knife maintains good contact
with the rotating diamond disk. Take about 5 seconds to make each pull if you have a six
inch (6”) long blade. Increase the time of each pull for longer blades or decrease the time
for shorter blades.
Make one pull of the blade in the left slot as described above and then repeat the same
procedure in the adjacent (right) slot of Stage 1. As you pull the knife thru the right slot,
(see Figure 2), hold the right face of the knife against the slanted right face of the slot. If
your knife, before sharpening, is not very dull you will find that only about 5 pairs of pulls,
alternating in the left and right slots of Stage 1, will be sucient to put a keen edge on the
blade. However, if the knife is initially very dull you may find that 10 or more alternating
pairs of pulls in the left and right slots of Stage 1 will be needed the first time as you
reshape and sharpen the old edge. Always pull the blade toward you. Never push the
blade away from you when using Stage 1. Before leaving Stage 1 it is important to examine
the knife edge to insure there is a small burr along one side of the edge.
Figure 3 illustrates how to check for the burr. Proceed as follows: If your last sharpening
pull was in the right slot there should be a small burr on the right side of the blade edge.
If the last pull was in the left slot there should be a small burr along the left side of the
edge. If there is no burr make another pair of pulls and again check for a burr. Repeat
making pairs of alternating right and left pulls until you create a small burr along the edge.
(Sometimes it is easier to create the burr if you pull the blade slower.) Make another single
pull and confirm there is a burr along the edge after each pull. Only then are you are ready
to sharpen in Stage 2.
Figure 3. Develop a distinct burr along knife edge
before sharpening in Stage 2 or 3. Burr can be
detected by sliding finger across and away from
the edge. Caution! See text.
