The 3,000 grit stone quickly establishes a micro-bevel and begins the polishing process, removing marks left by coarser stones. It only requires a few minutes of soaking before use, do not keep in water. Overall size 203 x 74 x 31mm. The Sigma Power Corporation in Tokyo originally designed these premium stones especially for sharpening high alloy steels. The resulting stones perform very well on the toughest steels. Significantly faster than any other stones, they are between two and five times faster than waterstones with less durable abrasive or stronger bonds. Sintered under heat and pressure, a Sigma stone readily releases new, aggressive particles during use. While these stones will wear slightly faster, their extremely fast cutting action more than compensates. Since you remove more metal with fewer strokes, the overall effect is reduced wear. Flattening these stones is an easy process.
