Leikkuukivet

Leikkuukivet, often translated as "cutting stones" or "sharpening stones," are essential tools used for maintaining and restoring the sharpness of cutting edges. Primarily associated with knives, axes, and other bladed implements, these stones are typically made from abrasive materials that gradually wear down the metal of the blade, re-establishing a fine edge.

The effectiveness of a leikkuukivi depends on its grit size, which refers to the coarseness of the abrasive particles. Coarse grit stones are used for significant repairs or reshaping of a dull blade, while finer grit stones are employed for refining the edge and achieving a polished, razor-sharp finish. Some leikkuukivet are made from natural materials like sandstone or novaculite, while others are manufactured from synthetic abrasives such as aluminum oxide or silicon carbide.

The process of using a leikkuukivi, known as sharpening or honing, involves drawing the blade across the surface of the stone at a consistent angle. This action removes microscopic amounts of metal, creating a new, sharp edge. Different sharpening techniques exist, including using one or two sides of the stone, employing water or oil as a lubricant, and utilizing specialized sharpening systems. Regular use of leikkuukivet ensures that cutting tools remain efficient and safe to use.
