Despite its unassuming appearance this stone is a delight to use. The generous size gives and extremely stable sharpening feeling and the purity of the stone ensures a lifetime of consistent results. This is a workhorse stone that could last a professional craftsman many years of sharpening and polishing and a hobbyist at least a lifetime. The stone is firm, but not so hard as to be too difficult for less experienced users. With forced slurry it is fast enough to erase 6k synthetic scratches and leave a pleasant kasumi and can be refined further into a fine glossy finish. This stone is suitable for a wide variety of applications ranging from knives to tools and razors.
Aesthetics & Other Notes
