An inspection and cutting apparatus, comprising: a rotatable knife supporting ring having a multiplicity of radially aligned knife guidance tracks, and each of said multiplicity of radially aligned knife guidance tracks are defined by opposing, generally parallel, spaced apart sidewalls; a reciprocally movable cutting knife reciprocally and moveably cooperates with one of said knife guidance tracks, and wherein the cutting knife has an elongated, main body having opposite first and second ends, two opposing sides, and opposite first and second peripheral edges, and wherein the second end of the main body defines a sharpened edge, and wherein the elongated main body further has an outside facing surface on each opposing side, and wherein a majority of the outside facing surface on each opposing side of the elongated main body is oriented in substantially the same plane, and wherein the outside facing surfaces of the elongated main body, and the knife guidance tracks are exposed to a source of water during operation of the inspection and cutting apparatus; and characterised by a convexly shaped protrusion integral with each opposing side of the elongated main body and extending parallel to the first and second peripheral edges of the elongated main body, each protrusion having a length dimension that is less than a length dimension of the elongated main body, and further having a first end that is spaced apart from the first end of the elongated main body, a second end that is spaced apart from the second end of the elongated main body, a first elongate edge that is spaced apart from the first peripheral edge of the elongated main body and a second elongate edge that is spaced apart from the second peripheral edge of the elongated main body and each convexly shaped protrusion further having a thickness dimension that causes each said protrusion to extend outwardly from the outside facing surface of the elongated main body beyond the plane of the outside facing surface; and in that each convexly shaped protrusion frictionally engages with an adjacent one of the opposing generally parallel spaced apart sidewalls of one of the multiplicity of said knife guidance tracks and maintains a space between the outside facing surface of the elongated main body and the said adjacent sidewall of the said knife guidance track so as to inhibit adhesion which is created between the outside facing surface of the elongated main body, and the said respective sidewalls of the said knife guidance track, when water wets the outside surface of the elongated main body, and the said spaced sidewalls of the said knife guidance track. a rotatable knife supporting ring having a multiplicity of radially aligned knife guidance tracks, and each of said multiplicity of radially aligned knife guidance tracks are defined by opposing, generally parallel, spaced apart sidewalls;
