How to Use the Wave Premium Sharpener

Step-by-Step Instructions

Step One

Move the elastic band to one side of the case.

Remove the cover and the sharpening angle adjustment wheel.

---

Step Two

Lift the ceramic rod vertically and install the adjustment wheel so that the triangle on the body points to your chosen sharpening angle.

You can find the recommended sharpening angles on the case cover.

---

Step Three

Place the cover in the hand protection position.

---

Step Four

Holding the knife vertically, make 5 strokes with the blade along the right side of the blue ceramic rod, moving from the heel of the blade to the tip.

Move the rod to the right and make 5 strokes along the left side of the blue ceramic rod.

Then make:

• 4 strokes on the right and 4 on the left;

• 3 on the right and 3 on the left;

• 2 on the right and 2 on the left;

• finally, 1 stroke on each side.

Finish by making several more single strokes, constantly alternating sides and applying minimal pressure.

If the knife is still not sharp enough, repeat the entire process from the beginning.

White Ceramic Rod

Pull out the ceramic rod, turn it 90° around its axis, and insert it back into the holder.

Increase the sharpening angle by at least one setting and repeat the procedure described in Step Four, this time using the white ceramic rod.

Step Five

Leather Strop

Remove the adjustment wheel and the cover.

Place the ceramic rod inside the case.

Reattach the adjustment wheel and place the cover upside down to gain access to the leather strop.

Important!
Stropping is performed in the opposite direction to sharpening.
Never push the cutting edge into the leather—always pull the blade backwards.

Draw the blade across the leather from heel to tip, maintaining an angle of approximately 45° relative to the leather surface.

Repeat this movement several times on each side of the blade.

How to Speed Up Sharpening for Very Dull Knives

If the knife is very dull, you can speed up the sharpening process using the blue ceramic rod.

Use both downward and upward strokes while keeping the blade in constant contact with the rod.

You can also apply more pressure and concentrate on the dullest parts of the blade—usually the areas that come into contact with the cutting board most often, especially the belly of the blade.

Continue sharpening until a burr forms along one side of the cutting edge.

Then switch sides and continue until a burr forms on the opposite side.

Try to make approximately the same number of strokes on both sides so that the cutting edge remains symmetrical.

To finish, remove the burr by making one stroke on each side, constantly alternating sides and gradually reducing the pressure to a minimum.

Cleaning the Ceramic Rod

In the areas where the ceramic rod comes into contact with the blade, its surface gradually becomes clogged with steel particles, causing the rod to sharpen more slowly.

For this reason, it is recommended to clean the ceramic rod periodically.

Any common kitchen cleaning product can be used for this purpose.

Apply the cleaner to the rough side of a kitchen sponge and scrub the areas of the rod where grey metal marks have appeared.
