Figures 7 to 11 are top views of modified envelopes that are used in the pencil sharpener of the present invention can be used.

In the various views of the drawing are the same parts are provided with the same reference numerals.

In the drawing / and in particular 'in the figures 1 to 6, a pencil sharpener 2o according to the invention is shown, which consists of a housing 22 made of plastic or consists of similar material and a conical guide part 24 contains · This guide part 24 has on its circumference an elongated part which delimits an opening 2g. The housing 22 also carries a blade 28, the Cutting edge 3o is connected to the opening 26.

The housing 22 can carry two opposite operating surfaces' $ c and 34. Both ends of the j? Ührun _fi steep 24 are open. The cutting edge j> o of the blade 2b extends beyond the smaller jind of the puehrsteiies 24. Underneath this cut edge is a sloping portion 56 that picks up lead or graphite dust and wood chips that are later thrown away.

The housing 22 of the pencil sharpener 2o is cast or in an injection molding process, or another process, manufactured with the blade 28 inserted into the mold and is firmly connected to the housing 22, so that no additional fastening devices such as screws or screw-like parts are necessary. The blade 28 is made up to the cut edge 3o during the manufacturing process almost entirely surrounded by the material of the housing, making them in a predetermined ratio remains firmly connected to the housing and is covered by the material of the housing so that it is neither dismantled can still be adjusted, and a plastic outlet at the guide openings 38 is excluded.

Holes or edge recesses may be provided in the blade 28 to form part of the housing Material to allow passage. The blade 4o in FIG. 7 has a cutting edge 46 and two bores 44 in some distance from each other.

The blade 46 shown in Fig. 8 also has a Cut edge 4b, two spaced apart holes 5o and an arcuate recess on which the Cut edge 48 on the opposite edge.

9 shows a further exemplary embodiment of a blade 54 »the one with a cutting edge 56 and several arcuate recesses 5ö on the cutting edge 56 opposite Xante is equipped.

In the embodiment of Fig. Io has the

Blade 6o one cutting edge 62 and several, at intervals, mutually standing recesses 64 with undercuts 66 in the outer edge opposite the cutting edge 62, whereby the interlocking connection between the blade 6o and the housing is improved.

In a similar way, the blade 68 in FIG. 11 has a sonic edge 7o with recesses 72 on the outer edge opposite the cutting edge 7o and additional recesses 74 on the narrow sides of the remaining outer edge, each recess 72, 74 having backsides 76, 78. . *

The use and mode of operation of the inventive Pencil sharpeners are clearly visible. Any blade shown in Figures 5-11 can be used in manufacture. any other blade with differently shaped or on others Places located holes or located on the outer edge recesses in a conventional manner in the cast or Pressing apparatus are firmly connected to the housing, with
