This small ceramic stone looks like a small concrete block, and to touch, feels about the same.
Useful for gross metal removal to correct damage to blade edges or as a stone to restore the clogged surface of finer stones, this stone is unique due to it being so hard and so coarse.
Use with caution...
*Supplied with #36 SiC loose grit for flattening and conditioning.
