NAIL FILE Filed March 26, 1935 J M fiero Patented Jan. 7, 1936 UNITED STATES PATENT I OFFICE 3 Claims.

This invention relates to nail files and the object of the invention is to provide a nail file of such character that it will not leave a feathery edge on the finger nail but on the contrary will leave a smooth edge.

A further object is to provide a device of this kind which does not trim the nail by filing. but by cutting or shaving the nail, leaving it smooth and not in need of any further trimming.

My invention is illustrated in the accompanying drawing, wherein Figure 1 is a face view of a nail file constructed in accordance with my invention and having circular perforations.

Fig. 2 is a fragmentary view of the cutting portion of the nail file but showing triangular perforations.

Fig. 3 is a like view to Fig. 2, but showing elongated slots or perforations.

Fig. 4 is a cross section through the instrument.

Referring to the drawing, in designates the body of the instrument proper which may have a form generally similar to the form of a nail file. I do not Wish to be limited to any particular form for this instrument. One portion of the instrument, as for instance, the portion II, is provided with very closely arranged perforations l2. These perforations in Fig. l are shown as being circular in form and are placed as closely together as is possible without overlapping. These perforations are cut cleanly through the material of the instrument and the opposite faces of the instrument are entirely flat and smooth. In other words, there is no burr constituting a Wall for the perforations.

In Fig. 2 these perforations are shown as being triangular in form instead of circular, and in Fig. 3 as being in the form of slots which may be inclined to the direction of use of the instrument.

While I have referred to this instrument as a nail file, and while it may be similar in form to the ordinary nail file and provided with a nail cleaning tip l3 at one end and a broad spatulate clear out to the edge of the implement and preferably in a straight line parallel with the edge so that it may cut in the corners of the nail without injuring the cuticle in any way.

It is to be noted that the perforations are so small that only an extremely small portion of the nail extends into a perforation when the device is in use and that the implement has the same efirect upon the nail as a file would. The 5 implement may be used, therefore, as a means of pointing a nail as well as a means for rounding it evenly. Other devices known to me have had openings made therein of relatively large diameter so that a large portion of the nail fits 10 within the opening and then by giving a bodily rotatory movement to the implement, the nail is trimmed, but with devices of this character, it is impossible to trim the nails in any other way except to round them. It is the fashion today to more or less point the nails, and an implement such as above referred to is incapable of this work. It is also pointed out that in my structure, the perforations have the same diameter or width on both surfaces of the implement so that either surface may be used for the purpose of operating on the nails.

An instrument constructed in accordance with my invention works on the principle of cutting instead of filing, the walls of the perforations I2 acting to out the nail as distinguished from rasping it, and this implement leaves the nail smooth instead of rough and feathery. In actual use, it has been found that it cuts better in the corners of the nail than filing does, and does not injure the cuticle.

It will not wear out as quickly as a file will, and it can be sharpened, which a file cannot. It is also readily sterilized and cleaned, as there are no crevices in which infected material might be hidden.

What is claimed, is:

1. A nail treating instrument comprising a blade-like member perforated over its whole area, the perforations being small and close together, and the opposite faces of the perforated blade being smooth.

2. A nail treating instrument of the character described, comprising a blade having a handle and point, a portion of the blade being formed with perforations extending directly through the blade, the perforations being small and set very closely together and the opposite faces of the blade being smooth.

3.-A nail treating instrument, comprising a blade-like member perforated over its entire area, the perforations being small and close together and extending close to at least one edge of the implement, the opposite faces of the perforated blade being smooth, the perforations having the 5 same area on opposite faces of the blade-like member.
