The 1×6 Nubatama stones are premium quality stone sized at 1″x6″x 6mm and will fit into any standard Edge Pro Apex, Edge Pro Pro, Hapstone Sharpener, TSProf guided sharpening systems, and with the Wicked Edge Uni Stone Holder Paddles. They can also be used as field stones, slip stones, and even slurry stones.
Nubatama Stones are all meant to be used with water only, and require a quick 1-2 minute soak before use. To optimize the effects of these stones, keeping the stone free of swarf will give them slightly more aggression while allowing a paste to form will maximize the finish. When utilizing the paste, don’t let it get too thick – keep it viscous with a couple drops of water.
