The guide rails are lined with plastic to minimize scratching on the knives during their use. Any time you remove one of the guide rails from your knife, rinse and clean it thoroughly to remove any residue from the stone that may remain inside the guide rail. To further insure that no residue remains, it is recommended that you pull a clean towel through the guide rail after rinsing. If you fail to remove all the residue from the guide rail, the residue may scratch the knife the next time the guide rail is used.
