The craft of sharpening a knife is as old as the knife itself. People have always found ways to keep their cutting and hunting tools as sharp as possible.
Knife sharpeners were not always around as we know them today but the procedure is the same. A knife is sharpened by sliding the cutting edge in an angle back and forth on a rough surface such as a stone. Some stones are better suited as blade sharpener and some stones do not make the best knife sharpeners.
In prehistoric times when knives were not as advanced as they are today, almost all stones were used as knife sharpening stones. Today we select only the best stones and use specific techniques to sharpen our knives.
Although stones are still used and some people use them as the best knife sharpener, our little knife sharpener can virtually sharpen any knife.

Some stones work better when wet and some other stones don’t need water at all. It depends on the stone itself. The Naniwa Super Stone, a Japanese water stone, is an excellent tool for sharpening knives that requires water for the sharpening process, but the stone does not need to be soaked in water prior to use as some others do.
Another fine stone for sharpening is the Shapton Glass Stone. Shapton, a Japanese company, uses finely graded ceramic which wears much more slowly than aluminum oxide or silicon based material that is found in man-made water stones. Because the glass stone is extremely dense it does not require soaking before use and has become the knife sharpeners best friend.
Knife sharpening water stones are not the only sharpening tools. A different stone type is the oil stone. As the word implies, to sharpen your knife, oil is being used instead of water. These stones are made of novaculite, aluminum oxide or silicon carbide and found mainly in Arkansas.
Although all sharpening stones vary in price and in performance, the diamond stone belongs to the more expensive stones. These stones contain small diamonds that are attached to the surface of the stone. There are different diamond stones and all perform differently.
The diamond sharpening stone comes in two basic types. One type, which is the most common, has diamonds that have small holes in the diamond that captures the swarf (metal debris during the sharpening process).
The second type is the continuous diamond surface (stone). This is practically the same but the diamonds do not have holes in it, providing a finer grid.
What do these sharpening stones have to do with our knife sharpener? The answer is simple. You do not have to purchase any of the sharpening stones because our knife sharpener does all the performances these stones do.
Simply put, one tool does all the work other tools combined can do.
