<\/figure>\n\n\n\nWhat are Japanese natural sharpening stones?<\/h3>\n\n\n\n
Japanese Natural Whetstones (JNATs for short) are stones quarried in the mountainous regions of Japan, especially around Kyoto, from ancient rock layers formed millions of years ago. They are used to sharpen knives, razor blades, axes, carpentry and blacksmithing tools.<\/p>\n\n\n\n
Unlike synthetic stones, Japanese natural stones consist of unique abrasive particles, almost without binding materials, which determine the nature of the grinding, smoothness and feel of sharpening.<\/p>\n\n\n\n
\n\n\n\n
Why choose natural stones?<\/h3>\n\n\n\n\n- Unique structure<\/strong> \u2013 every stone is different.<\/li>\n\n\n\n
- Natural form of abrasive particles<\/strong> \u2013 provides a smooth, clean cut.<\/li>\n\n\n\n
- Delicate control<\/strong> \u2013 you can precisely control the sharpening process.<\/li>\n\n\n\n
- Durability<\/strong> \u2013 Properly maintained stone lasts for decades.<\/li>\n\n\n\n
- Traditional heritage<\/strong> \u2013 working with materials that have been used for centuries.<\/li>\n<\/ul>\n\n\n\n

<\/figure>\n\n\n\nMain types of Japanese natural stones<\/h3>\n\n\n\n1. Awasedo<\/strong><\/h4>\n\n\n\nPremium finishing stones for the final finishing of a knife or tool. Extremely fine and smooth.<\/p>\n\n\n\n
2. Chu Nagura (\u4e2d\u540d\u5009)<\/strong><\/h4>\n\n\n\nIntermediate stone used before Awasedo. Has a medium-grained structure.<\/p>\n\n\n\n
3. Koma Nagura (\u7d30\u540d\u5009)<\/strong><\/h4>\n\n\n\nUsed to prepare the stone surface and generate a gentle suspension.<\/p>\n\n\n\n
4. Botan, Tenjyou, Mejiro Nagura<\/strong><\/h4>\n\n\n\nThese are softer stones used in conjunction with harder stones to create suspension and refine the final edge.<\/p>\n\n\n\n

2. Stone hardness<\/strong><\/h4>\n\n\n\nSofter stones are better suited for hard steel and intermediate stages. Harder stones are better suited for softer steels or for sharp final edge finishing.<\/p>\n\n\n\n
3. Level of abrasiveness<\/strong><\/h4>\n\n\n\nFrom coarse (for initial shaping) to ultra-fine (for final finishing).<\/p>\n\n\n\n
