Kits and Stone bundles

You can purchase the sharpener in a bundle with one of our stone sets. Each of the recommended stone bundles includes stones with evenly incremented grit (grain size). You can check our recommendation, depending on the steel hardness of your knives. We recommend Venev Dog Set for most customers.

If you already have a collection of sharpening stones, or if you plan to purchase stones of your choice, choose the Barebone kit with no stones.
