1×4 Amakusa and Binsui stone – Japanese Natural Stones (JNats) have a long tradition in sharpening, and have a huge range of stones available. Each stone’s name is indicative of it’s grit, which are labeled as Coarse, Medium and Fine. We’ve started out with 2 basic JNats, which measure 1×4″ x 6mm thick and fit into any standard KME stone holder and the Wicked Edge Uni Stone Holder Paddles. These stones can also be used as slip stones and field stones.
Japanese Natural stones are used with water only and just need a quick splash of water before use. JNats are also very dynamic in their capabilities, and entering into this realm of the rabbit hole is a whole new fun and exciting world.
The Amakusa stone is a Coarse grit, rated at about 800-1K grit. It is used as a cleanup stone from coarser grits, and emparts a basic working sharp edge.
The Binsui stone is a Medium girt, rated at about 1200-1500 grit. It is used to create a foundation for further sharpening, while leaving a respectable working sharp edge.
