Thread: Sharpen Your Own Mincer Plates and Knives

That system doesn't really work once a plate gets well worn, What happens is the working side if each hole in the plate rounds off, so to sharpen that plate you would need to remove a significant amount of material to remove the rounding in that working edge, not really practical using the system as shown. Once that rounding occurs the motor works a lot harder and the meat is not clean cut, it is mashed. With good quality plates it takes many a few hundred Kgs of meat to wear the plates, so it shouldn't hurt too much to bite the bullet and buy a new one. Ross is correct in what he says above. Also the cheaper plates are not precision ground so the holes are not sharp to begin with.
