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 will require it to be pushed through.
