I have a pair of almost new Norton Crystolon Oil Stones. One is fine, the other medium. These are for an early stage in honing, and you do need a finer stone for a finished edge. One side of each has seen light use, the other side is unused. They measure 8" x 3" x 1/2", and each comes in a plastic case, which has rubber feet, and serves as a sharpening base. Nothing wrong with them, they're just not my cup of tea. Selling for $10 each plus actual shipping from 13346. If paying with paypal, please add $1.
