DESCRIPTION OF THE CHEF’SCHOICE DIAMOND HONE KNIFE SHARPENER DC 320
This advanced Diamond Hone Sharpener has three motor driven sharpening Stages
1, 2 and 3.
- Figure 1. Inserting the blade in the left slot of the Stage 1. Alternate individual pulls in left and right slots.
- Figure 2. Inserting the blade in the right slot of Stage 1. Alternate pulls in left and right slots.
In Stage 1, motor-driven, highly effective diamond abrasive disks remove the dull edge and create a sharp fully faceted edge at the conventional 20 degrees. 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 further refined to create a razor sharp Trizor edge of increased perfection, sharpness and durability. In Stage 1, 2 and 3 there are two knife-guiding slots. These are referred to as the left and right slots that sharpen alternately the right and left side of the blade’s edge. When sharpening, 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 DC 320 gives you a very sharp edge and one that retains a significant bite for some of the more difficult cutting tasks.
USING THE DC 320 SHARPENER
Note : Always clean your knife before sharpening in the sharpener! For
your safety, keep your fingers clear of the blade edge at all times.
Try a practice pull through the sharpener with the power “OFF”. Slip the knife
blade smoothly into the left slot between the left angle guide of Stage 1 or
Stage 2. Do not twist the knife. Move the blade down in the slot until you
feel it contact the diamond disk. Pull it towards you lifting the handle
slightly as you approach the tip. This practice pull will give you a feel for
the spring tension. Remove the knife and read the following instructions
specific to the type of knife you will be sharpening.
STAGE 1
To sharpen, place the sharpener on the table gripping it securely with your
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 rotating 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. Each pull should be at a speed of
around one inch per second (6” blade=6 second pull).
Always pull the blade toward you. Never push the blade away from you. 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 through 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 sufficient to create a burr on the blade. However, if the knife is initially very dull you may find that 10 or more alternating pairs of
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. pulls in the left and right slots of Stage 1 will be needed the first time as you reshape and sharpen the old edge. 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, 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.) Confirm there is a burr along the edge after each pull. Only then are you are ready to sharpen in Stage 2.
STAGE 2
Once you have confirmed that a burr was formed in Stage 1, you are ready to
refine the knife in Stage 2. Proceed to sharpen in the left and right slots of
Stage 2 which have finer abrasive and sharpen at a slightly larger angle than
Stage 1 in order to create a small second bevel adjacent the knife edge. You
will likely find that only 1-2 pairs of pulls in Stage 2 will be sufficient to
create a small burr along the edge. Always sharpen alternately in the left and
right slots of Stage 2, taking about 6 seconds each pass for a 6” blade (see
Figures 4 and 5). Take longer for longer knives, and less time to pull shorter
blades through the slots. The burr will be slightly smaller than you
experienced in Stage 1. Pull slower if needed to develop a detectable burr
before moving to Stage 3. You will notice that the edge developed in Stage 2
is sharper than the edge formed in Stage 1. Once a burr is detected, move to
Stage 3.

STAGE 3
In general only two pairs of pulls (6” blade = 6 second pull) followed by one
pair of faster pulls (1-2 seconds each for 6” blade) in Stage 3 will be
necessary to obtain a razor sharp edge. Make alternating pulls rapidly in the
left and right slots. After doing so, the knife is ready to use.
RESHARPENING THE KNIFE EDGE
To resharpen, turn on the sharpener and follow the procedure for Stage 3
described above, making one to two (1-2) alternating pulls. Then test the edge
for sharpness. If necessary resharpen again starting in Stage 2 followed by
one to two (1-2) pairs of pulls in Stage 3. In severe cases with a very dull
knife you may find it necessary to repeat Stages 1, 2 or 3 as described above.
Generally you should be able to resharpen several times using only Stage 3
before having to resharpen in Stage 2 or 1.
SERRATED BLADES
Serrated blades can be sharpened in Stage 3 (see Figure 7). If the serrated
edge is on the left side of the knife, place in the left slot and vice versa.
Generally, three to five pulls in Stage 3 will be adequate. If the serrated
knife is very dull, more pulls will be needed.
Because of their saw-like structures, the edges of serrated blades will never
appear to be as “sharp” as the edge on a straight edge knife.
ASIAN BLADES
The sharpener is not recommended for Asian knives.
CERAMIC KNIVES
The sharpener is not recommended for ceramic knives.
SCISSORS
Do not attempt to use the sharpener to sharpen scissors. The Legacy Companies
does manufacture special sharpeners designed just for scissors.
BRANDS OF KNIVES
The sharpener will put an excellent edge on most conventional metal
Euro/American style knives regardless of brands, including Henckels, Wüsthof,
Sabatier, Lamson and Goodnow, Global, Russell Harrington, Chef’sChoice,
Messermeisser, Forshner, Mundial, Cuisinart, Kitchen Aid, Shun and many, many
more.
TEST FOR SHARPNESS
To test for sharpness and cutting ability of your fine edge knives, hold a
sheet of paper vertically by its upper edge and carefully cut down through the
sheet a small (but safe) distance from your fingers. A sharp edge (on a
straight edge blade) will cut smoothly without tearing the paper.
Alternatively try cutting a tomato. The knife should penetrate the skin of the
tomato and cut through it on the first pull without applying significant force
to the knife.
MAINTENANCE
- The exterior of the sharpener can be cleaned with a damp soft cloth.
- Periodically shake out and dispose of the metal sharpening dust by inverting the sharpener and lightly tapping it onto a newspaper, paper towel, or other paper sheet.
- No oils or other lubricating liquids are necessary with this sharpener.
- Figure 8. If your blade has a significant choil it may be helpful to place a finger behind it as shown when sharpening.
- Figure 9. Insert your index finger as shown behind the choil as the knife is inserted into the sharpening slot (see Suggestion 7.)
SUGGESTIONS
-
Always clean all food, fat and foreign materials from the blade surfaces before sharpening or resharpening. If badly soiled, use detergent and water to clean.
-
Always pull the blades at the recommended speed and at a constant rate over length of blade. Never interrupt or stop the motion of the blade when in contact with abrasive disks.
-
Carefully follow the detailed procedure to extend the useful life of your knives.
-
The edge of the knife blade, while sharpening, should remain in contact with the rotating abrasive disks as the knife is withdrawn from the guiding slot. To sharpen the blade near the tip of a curved blade, lift the handle up slightly as you approach the tip of the blade but just enough so that the edge as it is being sharpened maintains audible contact with the honing or stropping disk.
-
To increase your proficiency with the Chef’sChoice® DC 320, learn how to detect a burr along the edge (as described on page 5). While you might be able to sharpen well without using this technique, it is the fastest way to determine when you have sharpened sufficiently in the preliminary steps. This will help you avoid oversharpening and ensure incredibly sharp edges every time. Cutting a tomato or a piece of paper is a convenient method of checking for finished blade sharpness.
-
Use only light downward pressure when sharpening – just enough to establish secure contact with the abrasive disk.
-
If your knife has a significant choil you may find it helpful to place your index finger within or just behind the choil (see Figures 8 and 9) as you insert the blade in the sharpener (Be careful! The tip of the choil may be sharp). Your finger can act as a
“stop” and prevent you from inserting the blade so far that the choil area will catch on the front stop-bar of the sharpener as you withdraw the blade. A little practice will help you perfect this technique. As you insert the blade let your finger slide down the front of the sharpener. -
Do not attempt to use this sharpener to sharpen either ceramic knives or scissors.
