Q & A

  • Are Shapton Pro stones really original? Why are they not available on the web site of Shapton?

    Many end products are made by Gritomatic. We buy Shapton Pro sharpening stones from international distributors, perform the cutting, flattening and lapping, and mount the stones to blanks. We keep the names of the original sharpening stones in the names of the finished products, as well as the countries of origin of these stones.

  • Which Shapton Pro stones are good for extending Hapstone stone set? Is Shapton Pro 2000 okay as a next step?

    The first thing you should consider when combining stones from different brands is grit scale. Gritomatic and Boride use FEPA-F, while Shapton Pro uses a different scale. Shapton Pro 5000 is approximately equal to F 1200. That means that Shapton Pro 2000 will be a step down from FEPA 1200. You should consider Shapton Pro 8000 instead.
