If you have your own stones you would like to use with the ViperSharp system you can use these stone blanks to adhere to the stones. This product cannot be purchased as a standalone product. If you pre-ordered the ViperSharp then you can add as many of these as you would like to be shipped with your order but since I have shipping costs they will not be available to order alone at this price without shipping.
*Note -All Stones sold by ViperSharp will include the backplate. This blank plate is only needed if you want to use your own stones.
