Description

Technical Field

[0001] This utility model relates to the field of cutting tool processing technology, specifically to an automatic grinding device for a crescent-shaped meat slicing knife. Background Technology

[0002] A crescent-shaped meat cleaver is a knife with a unique curved design, typically used for meat processing, food handling, or specific cutting tasks. In meat processing, crescent-shaped meat cleavers can be used for operations such as deboning, slicing, or removing tendons. The curved blade allows for more flexible operation. During the manufacturing process of a crescent-shaped meat cleaver, the raw material needs to be ground.
