ABSTRACT:
The present invention encapsulates a razor blade in a relatively thick and durable plastic. In the plastic there are provided a number of comb-like projections which extend beyond the blade edge while still leaving the edge exposed between the protrusions. These protrusions serve to guard the blade from accidental contact, thereby enabling the present invention to be safely carried, even in a person's trouser pocket. Other features are molded into the plastic at the time of manufacture which allow the invention to be hooked onto a key ring and which further enable line of indeterminate length to be wrapped longitudinally about the invention. Due to low cost of manufacture, the present invention may be disposed of when the blade dulls. The plastic serves as a protective guard even after disposal, offering environmental resistance comparable to that of the blade. When the plastic degrades sufficiently to crack and separate from the blade, the blade will similarly have degraded and the edge dulled sufficiently to present substantially less hazard.
