Product information
The sharpening stone manufacturer SIGMA Power Corporation from Tokyo targets users of high-alloy steels such as HSS with their top range, Select II. With these stones, the effort to create a grinding feel similar to that of natural stones is also evident. Unlike resin, magnesium, or cement-bonded stones, the Select II have no binders. Instead, the vitrification process is applied to bind the grains in these stones. By increasing the viscosity during the cooling of the grinding stone mass, crystallization is prevented, resulting in amorphous material similar to the production of glass. This process is expensive but makes the Sigma Select II true steel eaters.
Not only is steel removed quickly, but the stone is also worn down rapidly – resulting in quite a bit of slurry during grinding – the price for speed! Therefore, it needs to be dressed more often, but this process is very quick with this stone.
