Sharpening Devicesnatural Japanese Stones»A blade and sharpening stone must be as perfect a match as bride and groom« according to legendary blacksmith,Shigeoshi Iwasaki. Finding the ideal pairing is no easy task in either case. Despite the excellent performanceof synthetic stones, many experienced sharpeners still prefer natural stones for sharpening their finestblades. Japanese sharpening stones are particularly renowned for their ability to harmoniously sharpen handforgedcarbon-steels. They can bring a blade’s full potential to the fore and allow the sharpening process itselfto become a pleasant ritual. The finest stones from the Honyama quarries are becoming increasingly difficultto acquire - we take great pleasure in still being able to offer these rare treasures.
