King Deluxe Red Waterstones are among the finest available. They are fired from
aluminum oxide abrasive carefully screened for consistent size mixed into a clay
matrix. Their size is 8" x 2- 5/8" x 1- 3/8" (207x66x34mm). These waterstones
are manufactured from a variety of fused abrasives which create a porous,
friable surface. This is important since, as the tool is rubbed on the stone,
the particles of abrasive are rounded and dulled.
