Description:  Use this diamond needle file set on all metals and even ceramics, stone, and glass!  Diamond needle files are excellent for all applications.  They file in all directions instead of just in the forward motion like regular needle files.  They also file quicker than normal needle files as they are coarser (only major consideration- files are coarser so they will not leave as smooth a finish after filing as regular needle files).
 
Approximate Size:  5 1/2" length, 1/8" handle thickness
Material:   Diamond coated steel with vinyl dipped handles
