The solution to the dullness of the blade of the i-mutton slicer

When sharpening the knife, add an appropriate amount of lubricating oil or liquid paraffin to the whetstone in advance to spread evenly.

Install a handle and a knife holder on the blade, which is convenient to hold the blade without hurting your hands.

When sharpening the knife, the staff holds the handle with the right hand and the tool holder with the left hand. It is the staff whose blade mouth faces the front of the staff to prevent injury. When grinding, let the front part of the blade move from the lower right corner of the whetstone to the upper left corner. , then flip at the end and grind the other side,

In the normal use process, the middle of the blade is used more and wears the most. In the process of sharpening the blade, the gap formed in the middle of the blade should be erased to prevent the formation of a crescent-shaped gap on the knife edge and affect the slicing effect of the mutton slicer.
