Made in Japan specifically for harder steels like HSS, these stones work beautifully on softer metals, too. They are made with very little binder so new, aggressive abrasive particles are constantly being released. They are the quickest cutting stones I have ever used. While these stones wear at a faster rate than others with more binders, this is offset by the extremely rapid cutting action. They simply get the job done before they have a chance to become out of flat.

Stone is 8 1/4” long x 3” wide x 1” thick.

Only needs a few minutes of soaking before use. Do not store in water.
