Whetstones have a long history, starting with stone tools polished with sand and stones during the Jomon period, and can be said to be one of the earliest tools.
There are various ways to classify whetstones, but they can be broadly divided into natural whetstones and artificial whetstones.
In the past, knives were sharpened by flattening rocks mined from hard geological layers. This is called a natural whetstone. On the other hand, a whetstone made by artificially processing hard particles (abrasive material) into square shapes is called an artificial whetstone.
There are many craftsmen who love natural whetstones, but the number of mining sites for natural whetstones is decreasing, and high-quality natural whetstones are sold at high prices. In addition, it is necessary to judge the quality by oneself, making it difficult for the general public to handle.
Therefore, most of the whetstones sold at supermarkets and home centers are artificial whetstones. Artificial whetstones have been created with the aim of achieving the sharpening quality of natural whetstones, and now whetstones are being produced that can sharpen knives as stably as natural whetstones.
In addition, unlike natural whetstones, there is no unevenness in performance, and you can choose a stable grain size, making it a very easy-to-handle whetstone.
