DRAWINGS

[0102] Further examples and advantageous embodiments of the invention are described in more detail below with reference to the figures. The figures show:

[0103] FIG. 1: A device for sharpening a blade of a circular knife in a perspective view from the top right,

[0104] FIG. 2: The device for sharpening the blade of the circular knife in a perspective view from the top left,

[0105] FIG. 3: The device in a perspective view with the recess for accommodating a honing surface,

[0106] FIG. 4: A view inside the holder,

[0107] FIG. 5: A view of the slot of the holder into which a circular knife is inserted, and

[0108] FIG. 6: A schematic representation of the circular knife.

[0109] FIG. 1 shows a knife sharpening device 1 for sharpening and/or honing and/or polishing the blade 2 of a circular knife.

[0110] In FIG. 1 to 6, the blade 2 of the circular knife also refers to the cutting surface of the circular knife.

[0111] The holder 32 of the knife sharpening device 1 is depicted as a housing 10.

[0112] The housing 10 comprises two housing halves 4, 5. The two housing halves 4, 5 are connected via a surrounding seal 6.

[0113] On an outer side 7 of housing half 4, a shoulder 8 is depicted.

[0114] The shoulder 8 extends relative to the longitudinal axis 9 of the housing 10 in continuation of a side 11 of a slot 12 in the housing 10, which has a straight profile.

[0115] In FIG. 1 to 5, the slot 12 extends transversely to the longitudinal axis 9 of the housing 10, preferably, but not exclusively, eccentrically into the holder 32. The holder 32 is depicted as the housing 10 of the knife sharpening device 1. As it engages with the holder 32, the slot 12 simultaneously engages with the housing 10 of the holder 32 of the knife sharpening device 1.

[0116] FIG. 1 to 3 show that in the area where the side 11 of the slot 12 has a straight profile, at least one housing half 4, 5 has a shoulder 8 on its outer side 7.

[0117] In FIG. 1 and 2, the shoulder 8 extends further, approximately at right angles to the longitudinal axis 9 of the housing 10, along the opening of the slot 12 for the insertion of the blade 2 of the circular knife at a front end 26 of at least one housing half 4, 5.

[0118] The shoulder 8 extends beyond the outer side 7 and/or the front end 26 of at least one housing half 4,5, which at least partially encloses the interior 18 of the housing 10.

[0119] The slot 12 in the representation of FIG. 1 has a straight side 11. The opposite side 13 of the slot 12 in the housing 10 has a curved profile.

[0120] The two sides 11, 13 of the slot 12 merge into a lower end 14 of the slot 12 relative to the longitudinal axis 9 of the housing 10.

[0121] Looking through the slot 12 from above right, relative to the longitudinal axis 9 of the device 1, a sharpening rod 15 is schematically visible.

[0122] FIG. 2 essentially corresponds to FIG. 1, with the difference that, when viewed through the slot 12 from above left relative to the longitudinal axis 9 of the device 1, a shoulder 8 is visible.

[0123] In the representation of FIG. 2, the shoulder 8 extends along the longitudinal axis 9 of the housing 10 along the side 11 of the slot 12, which has the straight profile.

[0124] The shoulder 8 extends beyond the outer side 7 of the housing half 4, which at least partially encloses the interior 18 of the housing 10.

[0125] The representation of FIG. 3 is essentially the same as that of FIG. 1, with the difference that the slot 12 in the housing 10 reveals the sharpening rod 15.

[0126] Additionally, a first sharpening insert 17 is visible, which is arranged on the sharpening rod 15.

[0127] A recess 3 is shown on an edge 28 of the housing half 4 of the housing 10 of the device 1, which serves to accommodate an additional sharpening insert 27.

[0128] FIG. 4 shows a view inside 18 of the housing 10.

[0129] The other housing half 5 of the housing 10 is shown with reference number 5. Recesses 19 for the insertion of screws (not shown) are depicted, which serve to connect the housing halves 4 and 5 of the housing 10 with each other.

[0130] In housing half 5, the slot 12 for the insertion of the blade 2 (not shown) is visible. The slot 12 has a straight side 11.

[0131] The curved side of the slot 12 of the housing 10 is labelled with reference number 13.

[0132] At one end 23, the sharpening rod 15 is pivotally mounted on a pin 20 of housing half 5 of the housing 10 of the knife sharpening device 1.

[0133] At its other end 24, the sharpening rod 15 is movably guided transversely to the longitudinal axis 9 of the housing 10 in an oblong hole 16.

[0134] In FIG. 4, the first sharpening insert 17 is arranged on the sharpening rod 15.

[0135] The sharpening rod 15 is shown in a rest position 21. In the rest position 21, a spring 22 pushes the sharpening rod 15 into the area of the slot 12.

[0136] The spring 22 is supported on housing half 5.

[0137] When the blade 2 is inserted into the slot 12 of the housing 10, the sharpening rod 15 is pivoted from the rest position 21 into a working position 25 via the oblong hole 16 against the force of the spring 22.

[0138] The movement of the sharpening rod 15 from the rest position 21 to the working position 25 and vice versa is guided by a pin 33 on the sharpening rod 15, which engages with the oblong hole 16.

[0139] The representation of FIG. 5 essentially corresponds to the representation of FIG. 4, with the difference that FIG. 5 shows the blade 2 of the circular knife inserted into the slot 12 of the housing 10.

[0140] Through the engagement of the pin 33 of the sharpening rod 15 with the oblong hole 16, the sharpening rod 15 is pivoted from the rest position 21 (not shown) into the working position 25.

[0141] FIG. 6 shows a schematic representation of the blade 2 of the circular knife with a surrounding burr 34.

[0142] The blade 2 of the circular knife can be sharpened and/or honed and/or polished using the device 1 to sharpen the circular knife.

[0143] The burr 34 in the concave section 29 of the blade 2 of the circular knife is sharpened and/or honed and/or polished by inserting it into the slot 12 of the housing 10 and placing it against the first sharpening insert 17 of the sharpening rod 15.

[0144] The burr 34 in section 30 at the back 31 of the blade 2 of the circular knife is sharpened and/or honed and/or polished by placing the blade 2 against the additional sharpening insert 27.
