King water stones were among the first Japanese stones introduced to the West. They are aluminum oxide abrasive in a resin bond. In our testing, they were effective in O1 steel but noticeably slower in tough alloys such as A2. The particles fracture and dull after a short period, performing like progressively finer grits, which allows you to move from a medium grit straight to a finishing stone. They are economically priced, require only a quick soaking before use, and are a good choice for honing softer tool steels or when cost is a concern.
This 8000x stone is our finest finishing stone.
The edge attained is noticeably better than an edge from any Arkansas stone and you get there faster.
It is 7" × 2 1/2" × 1/2" thick and is mounted on an 8" × 2 3/4" plastic base.
Made in Japan.
