Claims19
A rotary cutting apparatus comprising:
- (a) a cylindrical housing comprising an opening defined through a central axis of the cylindrical housing, wherein the housing is rotatable around the central axis and wherein the cylindrical housing comprising a plurality of slots defined around an outer surface of the cylindrical housing;
- (b) a plurality of blades coupled to and extending outward from an outer surface of the cylindrical housing, each of the blades disposed at an angle in relation to the central axis of the cylindrical housing, and wherein each of the plurality of blades is disposed in one of the plurality of slots;
- and
- (c) a rotatable bracket assembly comprising at least one bracket comprising an axle, wherein the axle is disposed within the opening, wherein the rotatable bracket assembly is rotatable about an axis non-coaxial with the axle.

A rotary cutting apparatus comprising:
- (a) a cylindrical housing comprising:
- (i) an opening defined through a central axis of the cylindrical housing, wherein the housing is rotatable around the central axis;
- and
- (ii) a plurality of slots defined around an outer surface of the cylindrical housing;
- (b) a plurality of blades positioned in the plurality of slots, each of the blades comprising:
- (i) a base disposed within one of the plurality of slots;
- and
- (ii) a cutting portion extending from the base, wherein the cutting portion is shorter than the base such that first and second shoulders are defined by the base and the cutting portion;
- (c) a first end cap disposed adjacent to a first side of the cylindrical housing, the first end cap comprising a first lip, the first lip configured to extend over an outer surface on the first side of the cylindrical housing and contact an outer portion of the cutting portion of each of the plurality of blades;
- and
- (d) a second end cap disposed adjacent to a second side of the cylindrical housing, the second end cap comprising a second lip, the second lip configured to extend over an outer surface on the second side of the cylindrical housing and contact an outer portion of the cutting portion of each of the plurality of blades.
