Size 32 Powermate Bone Collector Meat Grinder Knife, 2-Piece Brazed Edge. KASCO meat grinder plates and meat grinder knives are designed to minimize contact between the plate and knife, reducing heat and creating a cool cutting surface. This results in a fresher and more visually appealing product, which also extends product life. A sharp and long-lasting cutting surface helps produce consistent product and reduces waste from poorly cut and mashed meat.
