Abstract

A knife has a body forming a cavity, a blade with a cutting edge, and a holder forming a tool seat and movable relative to the knife body between an operating position with the tool seat in the cavity and a change position with the tool seat outside the cavity. An additional tool has at least two working parts and is provided with a holding part that can be fitted to the tool seat such that, in the operating position of the holder, one of the working parts is in a working position in which it projects from the body and can be used by a user while the other working part is in a stowed position inaccessible in the cavity and, in the change position, the tool is entirely outside the body and can be separated from the seat.

Claims

1. A knife comprising:

a knife body forming a cavity;

a blade with a cutting edge;

a holder forming a tool seat and movable relative to the knife body between an operating position with the tool seat in the cavity and a change position with the tool seat outside the cavity; and

a tool having at least two working parts and provided with a holding part that, in at least two different relative positions, can be fitted to the tool seat such that, in the operating position of the holder, one of the two working parts is fixable relative to the tool seat in a working position in which it projects from the body and can be used by a user while the other working part is in a stowed position inaccessible in the cavity and, in the change position, the tool is entirely outside the body and can be separated from the seat.

2. The knife in accordance with claim 1, wherein the tool is formed of sheet metal.

3. The knife in accordance with claim 1, wherein at least one of the working parts has at least one scoring edge.

4. The knife in accordance with claim 1, wherein the working parts of the tool are opposite one another and flank the holding part.

5. The knife in accordance with claim 1, wherein the holding part has a projection that fits complementarily with a recess of the seat.

6. The knife in accordance with claim 1, wherein the tool is held between a contact surface of the tool seat and a retaining surface of a cover of the body.

7. The knife in accordance with claim 1, wherein the holder also forms a blade seat holding the blade, and in the operating position the blade is held in the cavity with a portion of the cutting edge exposed and in the change position the blade is fully outside the cavity and separable from the holder.

8. The knife in accordance with claim 1, wherein the holding part of the tool is engageable in the two different relative positions in the seat in one of which one of the working parts is exposed in the operating position of the holder and in the other of which the other of the working parts is exposed in the operating position of the holder.

9. The knife in accordance with claim 8, wherein the working parts of the tool are the same shape.

10. A knife comprising:

a knife body forming a cavity;

a blade with a cutting edge;

a holder movable relative to the knife body and forming a tool seat;

a tool detachably held on the knife body, having at least two working parts, and provided with a holding part that, in at least two different relative positions, can be fitted to the tool seat such that either one of the working parts can be in a working position projecting from the body and can be used by a user while the other working part is in a stowed position inaccessible in the cavity; and

a pivot on the knife body and carrying the holder such that the holder can pivot between an operating position and a change position.

11. The knife in accordance with claim 10, wherein the holding part of the tool is engageable in the two different relative positions in the seat in one of which one of the working parts is exposed in the operating position of the holder and in the other of which the other of the working parts is exposed in the operating position of the holder.
