Read this! Do not place an order until you have read our Sharpen by Mail FAQ. (1) We do NOT sell replacement runners without the purchase of a custom radius. (2) We do not ship to addresses other than credit card billing address. It is your credit card company that tells us the shipping address doesn't match. Nothing we can do. If it doesn't your order will be cancelled. (3) Our ZC machine is out of service and it is unknown when it will be repaired.
