Stropping device of blade for safety razors

A stropping device of a blade for safety razors, capable of allowing an existing razor blade to be repeatedly used, is disclosed. The stropping device consists of a main body and an adhesive sheet attached on the back surface of the main body. A guide groove part is longitudinally formed on a front portion of the main body, while a protrusion is integrally and horizontally formed on a top portion of the main body. Also, side walls are formed at both side ends of the main body in such a manner that their outer surfaces are smoothly curved. A stropping plate member, produced from a leather material such as a natural or synthetic leather or suede, is attached on the bottom surface of the guide groove part by an adhesive means. In addition, a recess is formed on a rear portion of the protrusion in such a manner that a nail, driven in a wall in a house, is inserted into the recess.

BACKGROUND OF THE INVENTION 
1. Field of the Invention 
The present invention relates, in general, to a stropping device of a blade 
for safety razors and, more particularly, to a stropping device capable of 
allowing an existing razor blade to be repeatedly used, thus allowing a 
user to use an existing razor blade without forcing the user to change the 
existing razor blade with a new one when the razor blade is abraded. 
2. Description of the Prior Art 
As well known to those skilled in the art, a typical razor, having a knife 
shape, is designed for shaving hair from the face and legs. In the typical 
razor, when the blade of the razor is abraded, the razor is continuously 
used after stropping the razor blade. However, such a razor is problematic 
in that a user is frequently injured by the sharpened blade. Also, since 
the razor blade is not changed with a new one, the razor is easily fouled. 
In an effort to solve the above problem, a safety razor, having a 
configuration capable of exchanging an existing razor blade with a new 
one, is proposed and widely used. In a brief description, the safety razor 
includes a handle and a razor blade holder mounted to one end of the 
handle. A push button is mounted to the other end of the handle, while a 
disposable razor blade is detachably mounted to the razor blade holder. 
Thus, when the razor blade is abraded, the abraded razor blade is easily 
separated from the razor blade holder by the push button, thus allowing 
the existing razor blade to be effectively changed with a new one. 
However, the razor blade is frequently changed with a new one, thus 
unexpectedly increasing the exchange cost of the existing razor blade. 
SUMMARY OF THE INVENTION 
Accordingly, the present invention has been made keeping in mind the above 
problems occurring in the prior art, and an object of the present 
invention is to provide a stropping device of a blade for safety razors 
having a configuration capable of allowing an existing razor blade to be 
repeatedly used, thus allowing a user to use an existing razor blade 
without forcing the user to change the existing razor blade with a new one 
when the razor blade is abraded, and which reduces costs incurred by 
excessive blade changing. 
In order to accomplish the above object, the present invention provides a 
stropping device of a blade for safety razors, comprising: a main body; an 
adhesive sheet attached on a back surface of the main body and having a 
removable backing paper, so that the main body is selectively attached to 
a wall in a house after removing the backing paper; a guide groove part 
longitudinally formed on a front portion of the main body in order to open 
at its bottom end and having a width larger than that of a razor blade; a 
protrusion integrally and horizontally formed on a top portion of the main 
body; side walls formed at both side ends of the main body in such a 
manner that their outer surfaces are smoothly curved in order to allow a 
user to feel comfortable holding the device; a stropping plate member, 
produced from a leather material such as a natural or synthetic leather or 
suede, attached on a bottom surface of the guide groove part by an 
adhesive means; and a recess formed on a rear portion of the protrusion in 
such a manner that a nail, driven in a wall in a house, is inserted into 
the recess. 
The stropping device further comprises a cover member mounted to the main 
body in order to open and close over a front portion of the main body in 
such a manner that hinge pins provided at a lower portion of the cover 
member are individually inserted into holes formed on both side walls of 
the protrusion, respectively; and a mirror mounted on an inner surface of 
the cover member.

DESCRIPTION OF THE PREFERRED EMBODIMENTS 
FIGS. 1 to 3 are views illustrating the construction of a stropping device 
of a blade for safety razors in accordance with the first embodiment of 
the present invention. 
As shown in the drawings, the stropping device comprises a main body 1 and 
an adhesive sheet 5, with a removable backing paper 6, attached on the 
back surface of the main body 1. A guide groove part 3, having a width 
larger than that of a razor blade "R", is longitudinally formed on the 
front portion of the main body 1 in order to open at its bottom end. In 
addition, a protrusion 8 is horizontally and integrally formed on the top 
portion of the main body 1, while two side walls 2 are formed at both side 
ends of the main body 1. Preferably, the outer surfaces of the side walls 
2 are smoothly curved in order to allow a user to feel comfortable holding 
the device. 
A stropping plate member 4, produced from a leather material such as a 
natural or synthetic leather or suede, etc., is attached on the bottom 
surface of the guide groove part 3 by an adhesive means. Thus, the razor 
blade "R" is downwardly stropped along the stropping plate member 4 after 
abrading, thereby easily sharpening the existing razor blade "R". Also, 
the adhesive sheet 5 is provided with a removable backing paper 6 in order 
to selectively attach the main body 1 to any wall in a house after 
removing the backing paper 6. In addition, a recess 7 is formed on the 
rear portion of the protrusion 8 in such a manner that a nail, driven into 
a wall in a house, is inserted into the recess 7 of the main body 1. 
FIG. 4 is an exploded perspective view of a stropping device with a cover 
member in accordance with the second embodiment of the present invention. 
In this embodiment, a main body of the stropping device is identical to the 
main body of the above-mentioned stropping device illustrated in FIGS. 1 
to 3. Thus, a description of the main body of the stropping device is not 
deemed necessary, but a cover member, denoted by the reference numeral 10, 
is mounted to the main body 1 in order to open and close over the front 
portion of the main body 1. 
That is, the bottom end of the cover member 10 is hinged to the top end of 
the main body 1. In a brief description, the cover member 10 is provided 
with hinge pins 12 at its lower portion in such a manner that the hinge 
pins 12 are individually inserted into holes 9 formed on both side walls 
of the protrusion 8, respectively. In addition, a mirror 11 is mounted on 
the inner surface of the cover member 10, thus providing convenience to a 
user during travel or a business trip. 
As mentioned above, the stropping device of this invention is provided with 
a configuration capable of being attached to a wall in a house or being 
hanged on a nail which is driven in a wall in a house. Thus, it is 
possible for the user to take the stropping device along during travel or 
a business trip. 
In addition, the stropping of the razor blade is carried out in short time 
in such a manner that the razor blade is repeatedly drawn from the top end 
to the bottom end of the stropping plate member three or four times. 
Furthermore, the stropping device of this invention allows a user to use an 
existing razor blade without forcing the user to change the existing razor 
blade with a new one when the razor blade is abraded. 
Although the preferred embodiments of the present invention have been 
disclosed for illustrative purposes, those skilled in the art will 
appreciate that various modifications, additions and substitutions are 
possible, without departing from the scope and spirit of the invention as 
disclosed in the accompanying claims.
