Gransfors Bruks Ceramic Grinding/ Sharpening Stone GB 4034 ✓ Free 60 Day Returns ✓ Free Express Shipping Description: The Gränsfors Ceramic Grinding Stone is a man-made sharpening stone with two grinding faces: a course side (180 grit) for repairing damage and heavy wear, and a fine side (600 grit) for sharpening. The ceramic composite makes the stone both durable and strong. In contrast to natural sandstone, a ceramic grinding stone can be given a more precise grain size. Its shape is round and flat with a bevelled edge to prevent chipping. The fine side is 2/3 of the thickness, as this side is usually used and worn down most. The stone is normally used with water but can be used dry. The stone comes in a protective rubber case.
