Japanese Small Repair Stone (32mm x 70mm)

After frequent and prolonged use of synthetic and ceramic sharpening stones, the stones will begin to wear down and cave-in in certain areas depending on the user. A stone fixer or corrector is essential for preserving the longevity and quality of your sharpening stones by flattening the uneven surfaces. Sharpening knives on a concave stone may begin to warp and change the shape of your quality blades.
