King water stones were among the first Japanese stones introduced to the West. 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 basic stone for every shop, this green silicon carbide water stone can be used to take nicks out of plane blades, chisels or gouges preparatory to sharpening.
At 200x, it is ideal for basic tool shaping and removes material quickly.
A large stone, it is 8" × 3 1/8" × 2 1/8" and over 3 lb.
Made in Japan.
