How to judge whether the frozen meat slicer should replace the blade or sharpen the knife?

1. The thickness of the meat slices cut by the frozen meat slicer is uneven; there are many fragments during the slicing process.

2. During the slicing process, the meat does not eat a knife, and the meat is cut across the surface of the blade without being sliced.

3. Manually press the meat to slice normally. During the sharpening process, turn off the machine from time to time to check whether the blade of the frozen meat slicer is sharpened to avoid excessive sharpening.

When cutting meat in the future, if the above situations occur, it means that we need to replace the blade. If the effect is still not obvious after sharpening the knife, then consider replacing the blade to troubleshoot the frozen meat slicer.
