Suehiro Cerax.

Suehiro 'Cerax' sharpening stones are designed to be a reasonably priced, high quality and user friendly line of sharpening stones, and they meet that ideal very well.

Being of a moderately hard composition and composed of high quality ingredients, they are capable of working effectively with most blade steels including high speed steel and powder metal steels, and their slightly friable nature ensures they resist clogging, cut quickly in all situations and maintain a level of smoothness and consistency few other stones are able to match. 

In use they offer great feel and excellent flexibility, and are quite durable being resistant to heat, cold, rapid drying and most household chemicals.

Ideal for the first time stone buyer as well as the seasoned professional looking for a no nonsense, no hype sharpening stone to get their edges sharp.
