This manual sharpener is an easy-to-use dual-purpose tool.
The first opening (near the middle) is formed by 2 tungsten carbide blades, and is used to sharpen very blunt edges.
The second one is formed by 2 ceramic grindstones, to sharpen more precisely.
Insert the blade of your knife in the first opening, making a right angle with the sharpener. Start from the tip, and pull until the handle. Do it several times. To obtain a more advanced sharpening, lean the blade at 30° and do the same movements several times.
Then insert the blade in the second opening to get a very sharp edge. With an inclination of 110°, start over again the same movements, until you get a perfect sharpening. Then rinse your knife.
Watch out: You must not use serrated blades with this sharpener!!

The ceramic being a high-resistant material, this one may have recurse to different ways to get cared.
By example, your ceramic stoves might get cleaned in a dishwasher and so might your knives. Nonetheless, it will always be recommended to take care of your ceramic products, hand-wash, so as to guarantee the most important longevity possible.
To realize this, use a neutral soap and some hot water and then, apply a sweet and dried cloth onto the surface of your product so to dry it. Sometimes, you can also use some grease on the non-stick products by using oil vegetable.
What you should avoid to do : Never use neither bleach nor chlorine and wire brushes on your products made of ceramic or you will deteriorate the whole surface of your stove.
Finally and if you take care of your ceramic knives, always use a wooden cutting board and not a plate or a workstation.
Avoid to shock the blades by chinking them together or by dropping it accidentally. The ceramic knives can be dishwashed. To sharpen your ceramic knives, use a sharpener which fits cermaic blades and not either a traditional sharpening steel or a grinding stone.
Plastic and derivated
In case of a hand-wash of your items in plastic and derivated plastic, use a soft and non-abrasive sponge or you will scuff the plastic and then pour out some washing-up liquid before to rinse with some hot water.
Unless otherwise indicated, you also can put plastic elements into a dishwasher by placing them in a such way that they do not clink together or along with ustensils and cutleries. You will, therefore, avoid the scuffs.
What you should not do : These products do not have to enter in contact with flames (BBQ, gaz stove...).
To avoid scuffing your derivated plastic (melamine, polycarbonate and acrylic), do not use sharpening ustensils or abrasive ustensils like abrasive sponge and steel wool.
