Recommended Uses: Very light repairs, light bevel adjustments, early stone in polishing progression, toothy edges, very hazy Kasumi
Notes: A well known stone that is often used as an early stone in polishing progressions on wide bevels. These Binsui are best for knives, not swords, though. Binsui are slightly harder and finer than Amakusa, and are better served with a forced slurry. Reduce pressure and dilute the Togidoro to refine the toothy edge it will provide.
