- O _ '

In known such hand tools, the knife protrudes relatively far from the handle and forms a Risk to children or other users and it is common practice to use a removable cap or cover for protection to use, but this makes handling more difficult and this additional part is often lost. Another disadvantage is that the paper to be cut for cutting on cardboard or other soft material must be laid, since the cutting process also cuts and so destroyed. A lot of skill is also required, the right contact pressure when cutting, so that it is neither too big nor too small.

The object of the present invention is to create a hand tool of the type mentioned at the outset which does not have the disadvantages of conventional hand tools or only to a small extent.

To solve this problem, the invention provides that the knife is a maximum of 0.175 mm, but preferably between Protrudes 0.15 and 0.08 mm from the handle.

In a particularly advantageous embodiment more than 95 percent by weight of the knife in one

Saving arranged in the handle and held in the handle by a cover. The knife advantageously has a rectangular shape and is thus in the handle. . '£ arranged so that only one corner of the knife protrudes.

The hand tool can be manufactured particularly easily and economically with an aesthetically beautiful appearance if the handle and the cover are made of plastic and glued together with the knife are connected to each other. The cover can advantageously be held appropriately in the recess and the entire handle thus formed can have a smooth outer shape.

In order to always have the tool close at hand, it can be carried in the pocket or handbag in order to carry out the To be used for cutting paper, for example to slit unseparated pages from Books, newspapers, magazines or to open envelopes. For this purpose, the handle has a halfway flat corner surface from which the knife protrudes · The corner surface expediently goes from the tip of the handle and the distance between the

The handle protruding part of the knife from the point is approximately between 3.5 and 5.5 mm. To cut of paper, the hand tool can then be guided along with the corner surface on the paper.

With an expedient / isführungform of the hand tool a tongue is provided in the recess, which provides a counter bearing for one end of the knife. Can continue the handle can be provided with an opening, for example by attaching it to a key ring or Key holder.

The hand tool has a handle 10 made of injection-molded plastic. It has a recess 16 in which more than 95 percent by weight of a rectangular knife 11 is arranged and held by a cover 12. All of these parts can be glued together for easy assembly. The cover 12 is adapted to the shape of the recess 16, so that overall a smoothly shaped tool (tool with a flat surface is formed, wherein, as can be seen in particular from FIGS. 1 and 3, one corner of the knife 11 by a maximum of 0.175 mm, but preferably protrudes by 0.15 to 0.08 mm.

In the recess 16 there is also a tongue 13 which acts as a stop for one end of the rectangular knife 11 serves.

Although the knife 11 is not interchangeable, it can be made of cheap hardened steel with high Be made carbon content, so that a cutting capacity of more than 1000 m of paper is possible with it is.

For cutting, the tool is guided flat over the paper with its flat corner surface, whereby through the cutting edge of the knife 11, which protrudes only slightly from the handle IC, is only cut from a piece of paper, even if several layers of paper of normal thickness are stacked on top of one another, because the knife 11 only protrudes slightly from the handle 10, there is practically no risk of injury without special protection and there is also no risk of the knife breaking if it is not used properly. Also If you carry it unprotected in your pocket, there is no risk of injury and the knife will cause it 11 also does not damage the fabric of the pocket, since the contact pressure required for cutting is in the cutting area cannot be reached inadvertently.
