## Abstract

A cutter which is particularly suitable for raw sausage production. Setting out from a knife with a knee and two circular cutting curves of equal radius and an outer edge concentric to the pivot, the base point of a perpendicular drawn from the knee onto the radial through the tip having a spacing from the pivot which is at least 1/4 of the distance from the pivot to the tip, the special feature consists in the fact that the radials to the knee and to the tip enclose an angle of at least 60.degree.. This results in a particularly broad knife blade.

## Claims

### Claim 1

A cutter being rotatable in a circumferential direction about an axial point of rotation, comprising:
a cutting edge consisting of first and second cutting portions, said first and second cutting portion is each having only a convex curve shape having equal radii, said first and second cutting portions adjoining one another to form one knee therebetween projecting in the circumferential direction;
an outer edge concentric to the axial point of rotation and adjoining said second portion to from a kink therebetween, said kink being distal from the axial point of rotation; and
a curved rear edge adjoining said outer edge to form a tip therebetween;
wherein said tip and said axial point of rotation define a first radial line, and said knee and said axial point of rotation define a second radial line, said first and second radial lines forming an angle of at least 60 degrees therebetween, and wherein an imaginary line extending through the knee perpendicularly intersects said first radial line at a base point whose distance from the axial point of rotation is at least 1/4 the distance between the axial point of rotation and said tip.

### Claim 2 (depends on 1)

A cutter as defined in claim 1, wherein said kink and said axial point of rotation define a third radial line, said second and third radial lines forming an angle of at least 45 degrees therebetween.

### Claim 3 (depends on 1)

A cutter as defined in claim 1, wherein said curved rear edge has a curve apex, said curve apex and said axial point of rotation defining a third radial line, said second and third radial lines forming an angle of at least 40 degrees therebetween.
