The #12,000 grit Naniwa Super Stone, Whetstone is classed as a Super Fine grade stone.
S2 Super Stone is a series of sharpening whetstones especially suited for the final polishing stage, they offer high polishing effect and stay flat for long time.
This series of Whetstones from Naniwa Abrasives are made from the same high quality grit as the Naniwa Professional series but made from a softer resin with slightly less grit for those on a budget.
The Naniwa Super Stones do require light soaking, however they're not extremely thirsty. A soak for only a few minutes and they're ready to go. An occasional splash of water during use keeps them working smoothly. They should not be stored in water.
The stone is resin bonded with White Aluminium Oxide for premium cutting power.
The Naniwa Super Stone series of stones will begin to develop a dish after frequent usage, to maintain the stones a lapping plate is recommended to keep the surface flat for long life.
We suggest either the Jende Industries Glass Lapping Plate, Shapton Diamond Glass Lapping Plate or the Shapton NAORU cast iron lapping system for this process
