King Deluxe Stone 1000
I purchased the above hone, and sliced into four pieces. It is about 1/2" thick and about 4" x 2.5" in honing surface. (The back side has saw marks, is not entirely flat, and is not suitable for honing.)
Japanese stones are softer than US made stones and it is suggested to use water when honing instead of oil. The 1000 grit stone is used in the first stage of actual sharpening.
