Description
1(~790S~
This invention relates to tools used for cutting paper or similarly thin materials.
There has long been a need for a simple and handy tool for cutting the top sheet of a pile of papers or similar materials.
In particular, it is often desirable to cut the top page of a newspaper or a magazine which one is reading without cutting the pages below, for example, to cut out a valuable coupon or an in-teresting article. It is also desirable to be able to cut a coupon from a bond.
A conventional cutting tool, such as a pair of scissors, is often not available and in many situations is not even practical.
For example, to use scissors to remove a small clipping from the center of-a page, one must either start the cut from the nearest edge of the paper or stah the page near the desired article in order to begin the cut. ; r A simple device such as a single edge razor blade might be useful in some instances, but there would obviously be little to prevent the user from cutting not only the top sheet, but also one or more sheets below it. In addition, a bare razor blade can be quite dangerous.
Tools specifically designed for cutting articles out of newspapers have been suggested in the past. For the most part, these tools have been mechanically complex and consequently quite expensive to manufacture and to purchase. Many of these prior cutting tools have had sharp and pointy blades which protrude from the tool in a dangerous fashion. This inherently dangerous feature has made such tools particularly inappropriate for use by children.

A further problem with many earlier cutting tools has been the necessity of orienting the tool relative to the paper and maintaining that orientation while moving the tool along the line to be cut. This is often dificult and awkward and may make it difficult to see the area on the paper which one desires to cut.
Accordingly, it is an object of the invention to provide a cutting tool ~or cutting the top sheet of a pile of papers which is mechanically simple, uncomplicated to operate and inexpensive to manufacture.
It is a further object of the invention to provide such a cutting tool which is sa~e to use and which does not have sharp blade points protruding from the tool.
It is another object of the invention to provide a cutting tool which may be comortably held in the hand and easily operated.
It is yet another object o~ the invention to provide a cutting tool ~or cutting the top sheet o a pile of paper which is small, light in wèight and which may readily be carried in a pocket or purse.
These and other objects and features o~ the invention are accomplished according to the invention by providing a blade mounted ln a holder. The holder has first and second ends and a flat sur~ace along one side between the ends. The blade has a cutting surface and is mounted in the holder with at least a portion of the cutting surface extending from a predetermined part of the flat surace between the irst and second ends of the holder. When the ~ ~ 79 O 5~
flat surface of the holder is placed on a sheet of paper and slid along the paper, the cutting surface o~ the blade cuts the sheet of paper.
In one preferred ~orm of the invention, the holder has a body portion and a back plate which cooperate to form a slot near one end of the holder oriented at an angle to the flat surface and adapted to receive the blade. The blade, which preferably has an elongated shape, has a cutting surface on-one of the edges and is mounted in the slot with the long edges parallel to the slot and only a portion of the cutting sur~ace extending beyond the flat surface. The blade is held in place by the back plate.
The above description as well as further objects, features and advantages of the present invention will be more fully under-stood by reference to the folLowing description of the presently pre~erred, but nonetheless illustrative, embodiments in accordance with the present invention, when taken in conjunction with the accompanying drawings, wherein:
FIG. 1 is an exploded side view of a cutting tool of the present invention, showing the holder, the blade oriented relative to the holder, and the back plate, prior to assembly of the cutting tool.
FIG. 2 is a partial side view of the cutting tool showing the blade and the back plate secured in place.

Referring now to the figures, and mpre particularly, FIGS. 1 through 5, it is seen that the-cutting tool of the present invention includes a bLade 10 and a holder 11 having a body portion 12 and a back plate 14. Body portion 12 is preferably made of plastic and has two ends which, for"'convenience only, will be referred to as the left-hand and the right-hand ends. Body portion 12 has a flat surface 15 between the left-hand and right-hand ends and a roughly tear-drop shaped side face, and is thin relative to its length, as may be more ~ully appreciated in FIGS. 3, 4 and 5.
The right-hand end of body portion 12 is of such a size whereby it can be conveniently gripped between two fingers, as is illus~rated in FIG. 6. A hole 16 may be provided so that the cutting tool may be carried on a keychain or hung on a hook.
The left-hand end of holder 11 includes a slot 28, which, in the embodiment illustrated in FIGS. 1 through 6, extends to the left-hand end of holder 11. Slot 28 is oriented with respect to flat surface 15 at an angle X, which will preferably be an obtuse angle.
_ 4 _ .. . . . ~
~07905Z
Body portion 12 of holder 11 preferably has a recess 32, which receives a boss 34 formed on back plate 14, as described below. Slot 28 is preferably formed in body portion 12 of holder 11, although i~ will be appreciated that the slot could also readily be formed in back plate L4 .
Back plate 14 has a flat surface 17 which is aligned with flat surface 15 of body portion 12 when back plate 14 is mounted on body portion 12, as illustrated in FIG. 2.
Blade 10 is elongated and pre~erably rectangular in æhape, thus having long edges 24 and short edges 26, one of which has a cutting surface 18. It has been found that a blade which is approximately a quarter inch long by a tenth of an inch wide and one hundredth of an inch thick will function well in the cutting tool.
The cutting tool is assembled by placing blade 10 in slot 28 of body portion 12 with cutting edge 18 proximate to flat sùrface 15. Since slot 28 is preferably at an obtuse angle with respect to flat surace 15, cutting surface 18, which is preferably at substantially right angles to long edges 24 of blade 10, will also be oriented at an obtuse angle with respect to flat surface 15. It will be readily appreciated that blade 10 may be placed in slot 28 so that all or part of cutting surface 18 extends -beyond flat surface 15. It will be readily seen that if all of cutting surface 18 is allowed to extend below flat surface 15, blade 10 will tend to catch the edge of the paper rather than cut it.
It has been tound that most newsprint and similar paper 1'~)79052 has a thickness of approximately three thousandths of an inch.
Consequently, it has been found that the best results are obtained when cutting surface L8 extends approximately 0.004 inches below flat surface 15. This provides a blade which is not long enough to cut the paper underneath the top sheet. Furthermore, the blade does not constitute a danger to the user.
With blade 10 mounted in slot 28 of body portion 12 as indicated, back plate 14 is mounted to body portion 12 with boss 34 in recess 32 and is permanently sealéd using well known plastic forming techniques. Thus, when the cutting tool is fully assembled, blade 10 is embedded between body portion 12 and back plate 14 - with only a portion of cutting surface 18 exposed, as can be seen in FIGS. 2 and 3.
To use my cutting tool, body portion 12 is grasped near the right-hand end between two fingërs, and flat surfaces 15 and 17 are placed on the top sheet of paper Pl as illustrated in FIG. 6.
Blade 10 will pierce top sheet Pl but it will not cut the second sheet P2 or anything underneath it, since blade 10 does not protrude far enough to do so. The cutter need only be slid toward the right-hand end, in the direction shown by arrow 36 in FIG. 6, while keeping flat surfaces 15 and 17 flush with the paper~ The cutting tool will neatly cut the top sheet Pl as it is moved along the paper.
FIGS. 7 and 8 show another embodiment of the present cutting tool. To the extent that this embodiment is the same as the first embodiment, the same reference numerals are used. In this embodiment, slot 28 is displaced from the left-hand end of body portLon 12, a5 can best be seen Ln FIG. 8. With thLs arrangement, .. , . . . . .............................. .. ~ .. .. . ~

it will be readily appreciated that bLade 10 is surrounde~ by plastic material on four sides, instead of three sides as was the case with the previous embodi~ent, which provides additional support for the blade. Furthermo~e, since the cutting edge 18 of blade 10 is slightly offset from the left-hand edge of the holder, a portion of flat surfaces 15 and 17 are located to the left of cutting edge 18. This has the added advantage of holding down the portion of the paper that has already been cut, which normally might have a tendency to curl upward.
As will be readily apparent to those skilled in the art, the invention may be used in other specific forms without departing from its spirit or essential characteristics. For example, instead of orienting the slot and the blade at an obtuse angle with respect to the flat surface, it would be possible to orient them at an acute angle. Then, if the cutting surface is placed on the long edge of the blade which is nearest to the right-hand end of the cutting tool, a similar result will be achieved. The present embodiments are, therfore, to be considered as illustrative and not restrictive, the scope of the invention being indicated by the claims rather than the foregoing description, and all changes which come within the meaning and range of equivalents of the claims are therefore intended to be embraced therein.
