Used
in a household setting, the abrasives will last for many, many years
without need for repair or replacement. If the abrasives need
replacement, you may send the sharpener back to EdgeCraft and, for a
nominal fee, EdgeCraft will replace the abrasives, clean and lubricate
the sharpener and ship it back. The abrasives, however, should last a
very long time with normal household use.
