Yes we certainly can, and at no extra cost! However if your serrated knife has little or no serrations left (due to wear from use or over sharpening) we are unable to re-serrate the blade. If you prefer we can convert the knife to a plain edge knife, just let us know when you place your order if you would like us to do this. For clarity we will never convert a serrated knife to a plain knife without first asking you and getting your confirmation.
