Crystal File
Glass file

Diamond tip
(metal)

Metal file
''These photos are taken just above the tip of each nail and magnified 100 times. You can easily see the deep cut marks and ragged edges caused by competing files to the Crystal File. Without a doubt, the Crystal File leaves far fewer ragged edges than diamond and metal files, there are no deep scratches, like glass or emery boards do.''
