Frequently Asked Questions - Diamond Hone 478 Chef's Choice

How do I use the Chef's Choice Diamond Hone 478 knife sharpener?

Place the sharpener on a level surface about waist high. Hold the handle with your non-dominant hand. Insert the blade into Stage 1 slot (marked '1') centered, and move back and forth with light pressure until sharp. Then proceed to Stage 2 for honing with little to no pressure.

What are the two stages for?

Stage 1 creates a first bevel on the edge using diamond abrasives. Stage 2 hones a micro-bevel for razor sharpness. Always ensure the blade is adequately sharp in Stage 1 before moving to Stage 2.

How many strokes are needed?

For a typical dull knife, less than 25 full back-and-forth strokes in Stage 1 and fewer than 10 strokes in Stage 2. Extremely dull knives may require many more strokes in Stage 1.

Can left-handed people use this sharpener?

Yes. Turn the sharpener around so the handle is on the right side, then hold the handle with your right hand and the knife with your left. Follow the same sharpening and honing instructions.

How do I test if the knife is sharp?

Try slicing a tomato or cutting paper. A well-sharpened knife should slice cleanly without crushing or excessive force. Test periodically during sharpening.

What should I do with extremely dull knives?

Use only Stage 1 initially, making many strokes. Stop periodically to test sharpness by cutting paper. Once sharp, hone in Stage 2.

How do I sharpen thick blades?

After completing Stage 2 normally, turn the sharpener around and repeat Stage 2 with a few back-and-forth strokes from the other side, keeping the blade centered.

How do I maintain the sharpener?

Clean the exterior with a damp, soft cloth. Do not use oils or lubricants. The diamond abrasives are self-sharpening and require no maintenance.

What is the warranty?

EdgeCraft offers a 1-year limited warranty against defective materials and workmanship for normal household use. Proof of purchase required. Warranty void for industrial or commercial use.

Can I sharpen scissors with this model?

No. The Chef's Choice Diamond Hone 478 is designed only for knives with conventionally edged blades. Do not use for scissors.

INSTRUCTIONS

Congratulations! By selecting the innovative Chef's Choice® Manual Diamond Hone® sharpener, you will be able to enjoy the pleasure of knives that are sharper and stay sharp longer than those you may have sharpened using conventional manual sharpeners.

Before you begin ...

The Chef's Choice® Manual Diamond Home sharpener is “ambidextrous” - extremely easy to use whether you are a right- or left-handed person. 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. Hold the handle with your left hand (if right-handed) making certain that your left index finger and thumb remain safely in the recessed area of the handle. (If left-handed, see Suggestions on other side of sheet.)

CAUTION! Keep all fingers clear of the knife blade at all times.

Make certain the blade is clean, then proceed as follows:

1. Sharpening - Stage 1

Holding the knife in the right hand, place the blade in the first slot (marked number 1) and center the blade left to right in the slot. While continuing to keep the blade centered in the slot, move the blade back and forth in the slot along the entire blade length.

It is unnecessary to lift the blade after every stroke. Apply only light downward pressure on the blade and continue the back and forth action until the blade is sharp. Stage 1 creates a first bevel along the edge. Unless the knife is very dull, it will take less than 25 full back-and-forth strokes to sharpen in Stage 1. Do not proceed to Stage 2 until the edge is very sharp. It should for example, be sharp enough now to cut paper well (see Testing).

2. Honing - Stage 2

To hone the sharpened edge to razor sharpness, move the blade to the slot of Stage 2. This hones by creating a second “micro-bevel” along the edge. Maintaining the blade centered left to right in the slot, move the blade back and forth. Apply little to no downward pressure on the blade. If the blade is sharpened adequately in Stage 1, only a few, (less than 10), strokes will be necessary in Stage 2.

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.

* To test periodically for sharpness, hold a sheet of paper by its edge and carefully slice through it, making sure you cut a short but safe distance from your fingers. A sharp blade will cut smoothly without tearing the paper.

Suggestions

• If left-handed, turn the sharpener around, hold the handle with your right hand and the knife with your left, and follow sharpening and honing instructions above.
• With thick blades, it is sometimes useful after following the instructions for Stage 2, to turn the sharpener around, holding the handle with the other hand, and carefully repeat the sharpening process in Stage 2 with a few back-and-forth strokes from the other side. Be sure to keep the blade centered in the slot.
• Extremely dull knives can be sharpened in Stage 1, but many strokes may be necessary. Stop periodically and check the blade for sharpness by carefully cutting paper. Then hone the knife in Stage 2.

Resharpening

Knives can be resharpened by following the procedure described above, but, in general, fewer strokes will be required than for the initial sharpening.

ening, sharpening and honing angles are totally compatible for all models of the Chef'sChoice® knife sharpeners.
