OTIS A, TANNEEIIIII, OI CRANE, TEXAS NON'V'AOU RAZOR Application filed February 5, 1981. Serial No. 513,617.

This invention appertains to new and useful improvements in razors and the principal object of the invention is'to provide a razor blade which will eliminate the creation of .6 vacuum which occurs during theoperation,

of shaving, as when the blade is held close to the face. i

Another important object of the invention isto provide a razor blade which is perforated to increase the flexibility thereof which is desirable when honing or stroppmg.

These and other important objects and advantages of the invention will become a parent to the reader of the following speci cation.

In the drawing Figure 1 represents a perspective vlew of the improved razor. Fig. 2 represents a vertical sectional View taken substantially on line 2-2 of Fig. 12,

Referring to the drawing wherein like numerals designate like parts, it can be seen that numeral 5 represent the usual handle for receiving the blade 6, he blade 6 being prov-ided with the usual shank'7 andfinger engageable extension 8 which is pivotally connected to the handle 5 as at '9.

The blade is of the concave type and in carrying out the invention, it can be observed in Fig. 1-, that the thick back side 10 of the blade is the starting point for a plurality of grooves 11 extending inwardly on the blade and on opposite sides thereof to terminate at apertures 12 which extend through the blade midway between the longitudinal edges thereof. These openings 12 are arranged on a line passing longitudinally through the center of the blade and as is clearly shown in Fig. 1 additional openings 13 are provided through the blade at points between the grooves 11 and more toward the thickened back portions 10 and the openings 12.

It can also be seen, that the grooves 11 taper inwardly so as to merge with the face of the blade. Manifestly, in the act of shaving air can easily enter by way of the openings 12 and grooves 11 aswell as the opening 13 tion, in that they add to the flexibilit of the blade so that the same will easil ex and flatten out on the hone or strop w en in the act of honing or stropping the razor.

7 While the foregoing specification sets forth 65 the invention in specific terms, it is to be understood that numerous changes the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having thus described my invention, what I claim as new is A razor of the character described comprising a blade having a thickened edge portion, said blade being provided with inwardly ex- 65 tending grooves extending inwardly from the thickened edge portion, said blade being rovided with openings at the inner ends 0 the said grooves. v
