Synthetic Whetstones
• ARA-TOISHI (#140-600) - Rough stones are intended for experienced sharpeners as they are ideal for repairing damaged knives but can easily ruin a blade edge if improperly used.
• NAKA-TOISHI (#800-2,000) - Medium stones are required for establishing an edge and for bringing up an even burr necessary for sharpening. Larger stones provide a wider sharpening area.
• SHIAGE-TOISHI (#3,000-12,000) - Fine and super fine stones will remove surface scratches created by the medium stone and will polish the edge to a mirror-finish. A fine stone is necessary to sharpen traditional Japanese blades.
