Abstract

The invention provides a hand held razor-containing cutting device formed from two separable halves that are connected together during use along a centrally located longitudinally extending parting line. The two halves of the tool are held in contact with one another by means of frictional connecting elements that allow the halves of the tool to snap together for use. A pair of adjacent disassembly tabs are provided. One such tab is located on each half of the tool to facilitate separating the halves of the tool by prying the halves apart, usually with a screwdriver or similar tool that is placed between the tabs and then twisted to pry the tabs away from one another for separating the two portions of the cutting device so that the razor blade can be removed and replaced when required. The frictional connecting elements comprise C-shaped cooperating retaining studs that extend from one half of the tool and during assembly snap into openings provided in the other half.

Claims

1. A hand held razor holding cutting device, comprising:

a cutting device body including two mating portions that are secured in registration during use so as to contact one another along a parting line,

frictional connecting means operatively associated between the portions of the device for releasably securing the portions of the device in contact with one another,

wherein the parting line extends longitudinally and centrally of the device and is located between the mating portions of the device,

the connecting means comprise studs projecting from an inside surface of one of said portions and positioned to extend into aligned openings provided within the other portion of the device,

each of said studs comprises a split cylindrical connecting stud with a centrally located slot and a cylindrical center opening aligned with a center line of the stud to provide two laterally paced apart C-shaped stud halves,

said device having a razor blade receiving means for holding a razor blade between the portions of the device with a part of the blade exposed for cutting objects, and

a pair of adjacent cooperating disassembly tabs, one such tab being located on each portion of the device to facilitate separating the portions of the device by prying the tabs to force the tabs apart and thereby separate the portions of the device from one another for removing and replacing said razor blade.

2. A hand held razor holding cutting device, comprising:

a cutting device body including two mating halves that are in registration during use so as to contact one another along a parting line,

frictional connecting means operatively associated between the halves of the device for releasably securing the halves of the device in contact with one another,

said device having a razor blade holding means for holding a razor blade between the halves of the device with a portion of said blade exposed for cutting objects,

a pair of adjacent cooperating disassembly tabs, one such tab being located on each half of the device to facilitate separating the halves of the device by prying the tabs apart so as to force the tabs away from one another and thereby separate the halves of the device for removing and replacing said razor blade,

wherein the parting line extends longitudinally and centrally of the device and is located between the halves of the device,

the connecting means comprise centrally extending studs on one of said halves of the device positioned to extend into aligned openings provided on the other of said halves of the device,

each of said studs comprises a split cylindrical retaining stud having a cylindrical center opening aligned with a center line of each stud to provide two laterally spaced apart C-shaped stud portions,

lower parts of said mating halves form an elongated handle and each of said disassembly tabs extends downwardly from a bottom end of said handle along an axis aligned with a longitudinal axis of the handle, and

the device has a slot for guiding articles toward the razor blade, and

a reinforcing rib is provided on an edge of said slot for reinforcing the slot and to help in guiding an article that is being cut through the slot toward the razor blade.

3. The hand held cutting device of claim 2 wherein the device includes a chamber formed between said mating halves for holding replacement razor blades and a peephole is provided in at least one of the halves of the cutting device to enable a user to see whether or not replacement blades are contained within the cutting device.
