The cutting head portion defines a chamber. A cutting assembly is disposed in the chamber and includes a plurality of blades and a flexible spacer member disposed on the axle such that the blades rotate as the axle rotates. Each of the plurality of blades is separated from an adjacent blade by a spacer disposed on the axle. A grill assembly is coupled to the body and includes a grill and a grill cap.
