This is one of several paper towels needed. Just a glancing blow. Bought from Russia. Profile TechStudio This machine is pure genius! I do believe my decades long search for the perfect knife sharpening gizmo is over. I can die a happy man!!! P.S. I've been using the KME sharpening system for a number of years. It is very, very good. This is just more stable and easier to get a razor sharp edge.
