öljyhiomakivillä

Öljyhiomakivillä, literally translated as "oil sharpening stones," refers to a type of sharpening stone that is designed to be used with oil as a lubricant. Unlike water stones, which require water, oil stones are typically made from natural or synthetic materials that are less porous and do not absorb water. The oil serves to carry away the metal particles that are abraded during the sharpening process, preventing them from clogging the pores of the stone. This also helps to keep the stone cool, reducing the risk of overheating the edge of the tool being sharpened.

Öljyhiomakivillä come in a variety of grits, ranging from coarse to fine. Coarse grit stones are used for establishing a new bevel or repairing damaged edges, while finer grit stones are used for refining the edge and achieving a polished finish. The choice of grit depends on the material being sharpened and the desired level of sharpness. Common materials sharpened with oil stones include knives, chisels, planes, and other cutting tools.

The sharpening process with oil stones generally involves applying a thin layer of honing oil to the surface of the stone, then drawing the blade across the stone at a consistent angle. The process is repeated on both sides of the blade until the desired sharpness is achieved. Regular cleaning of the oil stone is important to maintain its effectiveness. This can be done by wiping it with a clean cloth or using a stone cleaner. Proper maintenance ensures the longevity and optimal performance of oil stones.
