1,002,377, I Patented Sept. 5, 1911.

article embodying this invention.



Specification of Letters Patent. Application filed March 6, 1911.

Pa-tented Sept. 5, 1911.

Serial No. 612,701.

of Cook, State of Illinois, have invented certain 'new and useful Improvements in Safety Corn-Trimmers, of which the fol-' lowing is a specification.

The main object of this invention is to provide an improved form of cutting implement for paring corns, bunions, calluses, and the like, and capable of cutting in various directions and. in confined spaces, as, for instance, between the toes, without danger of accidental injury. These objects are accomplished by the device shown in the accompanying drawings, in which Figure 1 is a perspective view of a toilet Fig. 2 is a sectional detail of the same, taken*- on theline AA- of Fig. 1. Fig. 3 is a transverse sectional detail of thesame, taken on the line B-B of Fig. 1.

In the form shown, the razor comprises a fiat blade 1 having an aperture 2 near its end, the edges of the aperture being beveled so as to provide a sharp cutting edge 3 adjacent to the lower face of the blade. The end of the blade is of rounded form, its edge being preferably substantially parallel with the adjacent part of the cutting edge of the aperture 2. The blade is also preferably curved or dished so as to be slightly convex on its lower side in the vicinity of the aperture, to facilitate the cutting operations. The cutting edge is preferably hollow ground on its upper side. When so I formed, unless the cutting edge is very dull, it can be readily sharpened by merely honing the lower face of the blade.

The handle of'the razor may be of any suitable form, but is preferably in the form of a file 4 with a nail cleaning tip 5, and the shank is provided with an indentation 6 in one edge, which serves as a finger-hold for either the filing or the cutting operations of the implement.

On account of the peculiar form of the cutting edgewand the fact that the blade is so narrow between its cutting edge and the sides and end of the blade, it is" possible to operate the blade in comparatively inaccessible places with comparative safety.

Although but one specific embodiment of this invention is herein shown and described, it will be understood that some of the details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined by the following claim.

A razor of the class described, comprising a flat blade having an aperture through it, the edges of said aperture being beveled on one side to provide a cutting edge around said aperture, and said blade being curved so as to be of double convex curvature on the side which isoppositethe beveled side.
