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.
A good general-purpose stone for cabinetmaking chisels and blades, the 1200x stone is nearly twice as fine as the 800x, but it still cuts rapidly.
For use after major nicks have been removed. Follow up with a 4000x or 8000x stone for a final finish.
Measures 8" × 2 1/2" × 1 3/8" and comes in a plastic box to keep it wet and ready for use.
Made in Japan.
