The Blunt is the easiest way to sharpener your knives. Simply attach any metal knife to the magnetic holder. Then glide the roller back and forth over your knife edge. Start with the diamond disc then finish with ceramic disc .

The Blunt Knife Sharpener will work great with most knives, including but not limited to any metal kitchen, cleavers, filleting and hunting knives with a smooth edge. Scissors and bread knives are not suitable.

Knives forged from Damascus steel have a particularly high hardness, which often leads to the question of how best to resharpen such hard blades. The Blunt has a high-efficiency diamond wheel. This material is harder than Damascus and as a result, even such exquisite knives can be sharpened with the Blunt. Also, the constant angle of 15, 18, 20 and 22 degrees ensures that only the cutting edge is resharpened and the expensive blade is not damaged.

Ceramic is not magnetic and as a result, knives with ceramic blades cannot be fixed to the magnetic holder. Therefore, the Blunt is not suitable for ceramic knives.

Yes, this is possible. Since Japanese knives are often sharpened on one side, you only want to resharpen one side of such blades. The blade can be sharpened alternately from both sides and thus also only on one side.

For taller knives, for example a large Chinese chef's knife, the Blunt Knife Sharpener can be underlaid with a cutting board so the grinder is elevated to the level of the cutting edge.

The first step is to sharpen a new constant angle of 15, 18,20 or 22 degrees for the first time. Most knives have a certain angle from the factory, which is between 15 and 22 degrees, but it is not always consistent. The first sharpening therefore takes between 2 and 6 minutes. For special blades with high hardness, such as Damascus, it can take up to 10 minutes. From the second use, after the knife has become a little dull again, the re-sharpening takes only a few moves forward and backward, because the grinding angle is already given by the first re-sharpening.

Diamond is the hardest material on the planet and is considered the most durable sharpening material for quality kitchen knife steels. If the Blunt is used properly, the diamond wheel does not need to be replaced.

The Blunt Knife Sharpener is not suitable for serrations. The serrated heads of the bread knives are ground off and the surface of the diamond sharpening disc wheel can be damaged.
