I lost the magnetic tip and guide rod to my DMT diafold sharpener. Didnt see it listed as a part in their catalog, so I called them up. In less than a minute, they took my name and address and said they'd send out the part free of charge! That means a lot to me and as long as I need something to do with sharpening or knife supplies, and DMT makes it, they'll get my business :thumbup::thumbup::thumbup:
