Lee Valley King 1000x/4000x Combination Water Stones

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.

For someone who wants to try water stones for the first time, or for someone who wants a more portable stone system, a combination stone is an economical answer.

With 1000x on one side and 4000x on the other, this stone gives you a self-contained sharpening system.

Two sizes are available. The standard combination stone is 8″ × 2″ × 1″. The large one is 8 1/4″ × 2 3/4″ × 2″.
