Claim:
An apparatus for cutting extruded materials, comprising: a generally disc-shaped knife holder made of a first material having a rotational axis, a circumference, and a pair of faces; a plurality of generally rectangular channels formed along the circumference of the knife holder, wherein each channel extends longitudinally from the rotational axis at an angle with respect to at least one of the faces, and wherein the rectangular channels are equally spaced; a plurality of extruder knives made of a second material, wherein: the second material is harder than the first material; each extruder knife has a length where the majority of the length extends beyond the circumference; each extruder knife has a first end that is brazed into one of the channels; and each extruder knife has an opposite second end that is free-floating; and at least two cutting edges on each extruder knife, wherein the cutting edges define a pair of generally parallel cutting planes, where each cutting plane is generally parallel to at least one of the faces so that the apparatus for cutting extruded materials is reversible.
