The Cerax Waterstone by Suehiro Niigata Japan is renowned for its fast cutting surface, its longevity and a reputation for consistency and high quality.
These stones hold their shape well and still cut quickly enough to create a burr in a reasonable number of strokes.
The Cerax Stones do require 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.
Cerax is packaged with a small Nagura stone, which is used for unclogging the stone if particle material becomes embedded during the sharpening process.
The Suehiro Cerax 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
