Gesenryo Tomae Natural Japanese sharpening stone

Tomae (the name of the rock layer) is a type of natural Japanese whetstone, often used for finishing sharpening due to its excellent properties. The stone has a balanced hardness and fineness, making it suitable for a variety of applications, including finishing sharpening kitchen knives and other tools. For razors - pre-finishing.

Natural Japanese whetstones (Jnats) are extracted from geological layers formed over hundreds of millions of years. Their properties vary depending on the region in which they were mined, so the results may vary. Such stones give knives a more beautiful finish and a finely honed edge, which is why they are valued by sharpening enthusiasts.
