Oil stone
An oil stone is a whetstone and used for sharpening blades and tools, such as from carving knives, planer knives, chisels and scrapers . Oil stones are fine, hard grinding stones for the final honing, which smooth and give the cutting edge the final sharpness. To do this, you put petroleum, white oil or another thin, non-resinous oil on the surface of the oil stone. An oil stone is normally used with oil, but some oil stones can also be used alternatively with water or dry, depending on the quality and intended use. Oil stones made from different natural stones or synthetic materials are available in many different grain sizes, synthetic oil stones also come in two different grain sizes.
The Arkansas oil stones come from quarries in the US state of Arkansas and consist of almost 100 percent silicate . The rest is made up of traces of bauxite , calcium and magnesium . This stone is very hard, so you can grind against the cutting edge without the steel digging in.
