We are currently not offering cutter sharpening but have provided links to a couple of how-to videos. You'll know your cutter is dull if: If it is harder to feed produce through the cutter, If there is excessive heat build-up, If there is obvious damage: nicks on the cutting edges, Note: The NW cutter does not need to be razor sharp and will work fine with some nicks and dings; the cutting edge should form a sharp corner. Inspect the edge if more than 50% of the edge is nicked; the cutter requires sharpening. A sharp cutter will pull produce through; a dull one will require it to be pushed through. -- SGF is not sharpening Norwalk cutters at this time.Here are two videos showing how to do it:1. https://www.youtube.com/watch?v=CkX0NXV74tU2. https://www.youtube.com/watch?v=uw4lT_Lwz_A
