You can resharpen your ceramic knife by using our resharpening service. Only Kyocera advanced ceramic knives can be sharpened with this service.

These knives are made of an advanced, high-tech ceramic called zirconium oxide (also called zirconia). Zirconium oxide is extremely hard, wear resistant, and chemically inert. For the technically minded, zirconium oxide has a hardness of 8.2 mohs (vs. steel at 5-6 mohs and diamond at 10 mohs). See similar questions...

There are many ways to sharpen our knives and no one way is better than any other. Actually because our knives are sharpened on one side only, people tend to think they are harder to sharpen. It is actually easier, since you are only dealing with one side. It's just different, not any more difficult. We are always asked about different sharpening systems and fixtures. Well, there are so many that we cannot be familiar with them all. See similar questions...

No, since we would be handling all of your sharpening needs you will have no reason to continue to maintain your current sharpening machines. This will not only reduce costs, for machine upkeep, but will also free up the existing space, that is currently dedicated for these machines, for other more important tasks.

Sharp knives are safer than dull ones because dull knives require more pressure for cutting, which can result in slipping. Sharpening knives with a sharpening steel can seem difficult at first, but it’s actually quite easy once you get the hang of it. Pull the knife down & across the sharpening steel in a slight arc, pulling the knife handle toward you. Stroke the entire blade edge from base to tip. See similar questions...

Yes and no, conventional sharpening steels and domestic knife sharpeners have virtually no effect on a ceramic blade especially if the edge has become chipped. Diamond sharpening steels do work, but the best option is the CATRA spiral knife sharpeners such as the CATRASHARP. These units quickly and accurately restore a worn and chipped edge to its factory condition. However they do require fitting with finer diamond wheels than the standard ones supplied originally.

Tests performed in EdgeCraft's laboratories demonstrated that Chef'sChoice® cutlery edges are more durable than ceramic knife edges. And, because of the inherently brittle nature of ceramic, they are prone to fail by chipping. Unlike Chef'sChoice® Trizor® cutlery, ceramic knives cannot be sharpened by any available conventional methods. See similar questions...

Sharpening is a trick to increase the apparent sharpness of an image by increasing the contrast around areas that look like edges in a photo. There are many reasons for doing this, the most obvious of which is that judicious use of sharpening can make a photo more pleasing to the eye. Image resizing also tends to soften edges, so it is often necessary to sharpen an image after resizing. See similar questions...

Speedheater scrapers are only beveled on 1 side. The following methods can be used to sharpen the blade: Remove the blade from the handle. Place a piece of sandpaper (150 - 220 grit) on a flat surface, and rub the back (non-beveled side) of the blade in circles. This method is the simplest, but if the blade is very dull, it can take some rubbing, since you are wearing away the backside of the blade. See similar questions...

It is highly recommended to replace the blades rather than sharpening them. Once a season is a good time to do it or when dull. Sharpening the blades will reduce their balance, which will increase mower noise, vibrations and can lead to damaging the mowing motors as well as shortening the available work time for a fully charged battery pack. PowerMow.com recommends that you replace your blades at the start of every mowing season to assure a quality cut year after year. See similar questions...

Your image should be sized to 220dpi at the size you're going to print it. Zoom the image to 100% so that you can see every pixel in an area of your image. Select Filter/Sharpen/Unsharpen Mask. Adjust the sharpness parameters without over-sharpening. Typical values are 100-150%, 1-2 pixel radius, and a 0 level threshold. See similar questions...

How often you sharpen your knife and how you sharpen your knife largely depends on what you were cutting and how many times you cut with the blade. However, MIL-TAC highly recommends frequent light sharpenings and never let the blade become completely dull. This will ensure that your blade is always sharp. Dull blades are far more dangerous than sharp blades and can cause problems and even injury during use. See similar questions...

Technically, any fine grinding stone will sharpen your katana, but usually is not recommended. this is because you want to keep the clam shape fo the sword, and not have a slight wave (if done improperly). Use a ceramic cross-bar knife sharpener with crossbeams, so that both sides are sharpened at the same time. It will also take fewer strokes to sharpen a blade this way, which saves metal.

Even though it looks like you can sharpen the Fantastix, it is not recommended. Think of them as a cross between a paintbrush and a marker. See similar questions...

You can use a small diamond file or a stone in each flute of the cutter. Some cutters are made in such a way that the backsurface of the cutting edge is not flat but rounded which makes it much harder, and which is why I don't like certain mills. Try not to touch the front surface of the cutter if you can avoid it, they need to be even and square. If necessary, remove the center barrel, set the cutterhead down on a stone and move it around a little, VERY LIGHTLY is the key word here. See similar questions...
