b) a second cylinder, having a second cylinder inner diameter, a second cylinder outer diameter, a second cylinder wall thickness therebetween, a second cylinder height extending from a second cylinder distal base portion to a second cylinder proximal end, the second cylinder distal base portion being co-planar with a second cylinder imaginary base plane (C-C), the outer diameter of the second cylinder positioned within the inner diameter of the first cylinder such that the first and second cylinders (38, 40) are co-axial to the central longitudinal axis (A-A), the first cylinder imaginary base plane (B-B) being more distal than the second cylinder imaginary base plane (C-C) along the central longitudinal axis (A-A); and c) i) a series of cutter blades, each having a proximal portion, a distal portion, a length therebetween, the series of cutter blades positioned circumferentially around the outer diameter of the second cylinder, between the inner diameter of the first cylinder and the outer diameter of the second cylinder, such that a cutting surface extends along the distal portion, parallel to and between the first and second imaginary base planes (B-B, C-C); or ii) a cutter disc having an inner disc diameter, an outer disc diameter and a planar disc surface therebetween, residing between the inner diameter of the first cylinder and the outer diameter of the second cylinder, such that the planar surface of the cutter disc is parallel to the first and second cylinder imaginary base planes (B-B, C-C), a plurality of cutting teeth being positioned through the planar surface of the cutter disc, each cutting tooth having a tooth opening extending through the planar surface of the cutter disc and a tooth cutting surface extending away from the planar surface of the cutter disc towards the first cylinder imaginary base plane (B-B). a) a first cylinder, having a first cylinder inner diameter, a first cylinder outer diameter, a first cylinder wall thickness therebetween, a first cylinder height extending from a first cylinder distal base portion to a first cylinder proximal end portion, the first cylinder distal base portion being co-planar with a first cylinder imaginary base plane (B-B), and a central longitudinal axis (A-A) therethrough;
