Description

Technical Field

[0001] The utility model relates to the technical field of files, in particular to a double-oblique cross file. Background Art

[0002] A file is a common hand tool, mainly used for surface processing of metal, wood, plastic or other materials. The surface of the file has many tiny teeth, which can be used for grinding and trimming workpieces. A double-bevel cross file usually refers to a file with teeth arranged crosswise in two different directions. Due to its specially designed tooth pattern, the double-bevel cross file can provide more uniform grinding and trimming effects.

[0003] However, when using the double-bevel cross files currently available on the market, most of the workers need to hold the files in hand to grind and trim the target workpiece, and in the initial rough processing stage, the workers need to use the files repeatedly to grind and trim the surface of the workpiece, which may cause labor intensity for the workers. Moreover, for files with only a single cylindrical handle, long-term use may cause unstable grip of the workers' hands, which may reduce the grinding and trimming quality of the workpiece.
