Teroituslevyllä

Teroituslevyllä, commonly referred to as a sharpening plate or whetstone, is a surface used to sharpen cutting tools, most notably knives and chisels. These plates are typically made from abrasive materials such as natural stones, ceramic, or synthetic compounds. The process of using a teroituslevyllä involves moving the edge of the tool against the abrasive surface, gradually removing metal to create a finer, sharper edge.

The grit of a teroituslevyllä refers to the coarseness of its abrasive particles. Coarser grits are used for repairing damaged edges or for initial shaping, while finer grits are employed for refining and polishing the edge to a razor-sharp finish. Different types of teroituslevyllä require different methods of use. Oil stones, for example, are lubricated with oil during sharpening, while water stones use water. Ceramic plates may require no lubrication or a specific type of cleaning agent.

The angle at which the tool is held against the teroituslevyllä is crucial for achieving the desired sharpness and edge geometry. Maintaining a consistent angle throughout the sharpening process is key to producing an effective and durable edge. Proper technique and practice are necessary to master the use of a teroituslevyllä and achieve optimal results.
