DETAILED DESCRIPTION OF THE INVENTION

[0017] A layer of hard clean metal, advantageously Cr or Ti, or another non-corroding and inert metal, in a thickness ranging from 0.5 to 2 m, advantageously with a thickness of 1 m, is applied to the glass body 1 of the file made of float glass (note: the glass can be chemically or thermally hardened as far as to a matt finish, the hardened glass cannot be used prior to other operations) in the form of an elongated plate 2 with a sharp, bevelled or rounded edge 3, advantageously using a file with a width of 8 to 20 mm, with a degreased surface free from contamination, creating a pattern of circular spot facets 5 with a diameter ranging from 1.5 to 3 m, advantageously with the diameter of 2 m, separated by spaces from each 6. The glass plate 2 with such deposited metal forms the basis for chemical treatment of the other opposite side of the plate and the formation of an abrasive surface with a roughened surface 4 on this other side of the plate 2. The abrasive surface can also be formed on the same side of the glass plate 2 to which the metal is not applied, providing the metal is only applied to a part of it. In order to protect the metal-plated side, it is necessary to mask the metal-coated surface with an acid-resistant wax (e.g. Masking wax yellow), or an acid-resistant plastic label, or a label and wax combination. It primarily depends on the size and shape of the surface area that needs to be protected. If the file with a grip or handle is required, such handle can be covered with regular plastic adhesive tape to be removed after matting. And again, even the handle can be masked using an acid-resistant wax (e.g. Masking wax yellow). Such prepared plates 2 are then matted in a mixture of hydrofluoric and sulphuric acids.

[0018] The formation of an abrasive surface on the other side of the plate or on a part of the same non-metal surface is to be created by etching, whereas the etched micro-structure of the roughened surface 4 is isotropic. The average width of the elements of this etched micro-structure profile, expressed by the RSm parameter, is in the range of 150 to 300 m, and the average height of the profile elements, expressed by the Rc parameter, is in the range of 30 to 120 m.

[0019] The average width of the etched micro-structure profile elements of the roughened surface 4, expressed by the RSm parameter, is advantageously 220 m, and the average height of the profile elements, expressed by the Rc parameter, is in the range of 70 to 90 m.

[0020] The masking wax or label needs to be removed after the abrasive surface etching.

[0021] The glass plate 2 can advantageously be thermally or chemically tempered (hardened), which achieves a higher resistance to fracture or breakage.

[0022] The glass file can be provided with a decoration selected from the group consisting of ground, engraved, painted or sand-blasted decoration, printing, decal transfer, glued-on rhinestones, jewels, metal, plastic or natural-stone accessories.

[0023] A combined file with a polisher produced in this way has the extraordinary properties of a glass file and simultaneously an effective nail polisher, which can advantageously also be used to polish the nail edges making them fully smooth, split-free, and much more resistant to eventual nail infections.
