The Nubatama Stones are premium accessory stones custom cut to fit the KME Sharpener, but can also be used as slip stones and pocket stones. They are 1″x4″ and 1/4″ thick. They also fit the Wicked Edge Uni Stone Holder Paddles.
Nubatama stones are meant to be used with water, and work best with a quick 1-2 minute soak before use in most cases. When using, start with a few drops of water on the stone. For more aggression, keep the stone clean during use, and allow a paste to form for squeezing out more refinement. For 1×4 Japanese Natural Stones, Click this link.
