This thread has reminded me of a tv program I saw some years ago.An Italian program where they visited a small museum .There was a large collection of knives which were used to butcher pigs.Each knife had a specific purpose for the various cuts and they numbered at least thirty knives !! I wish now I had more information about the collection....Every part of the pig is used , of course, even the skin. We see in America recipes for "italian sausage" which always make me laugh since there must be at least 1000 types of sausage in Italy ! That includes interesting things like zampone which is made by removing meat and bone from the lower leg,leaving the skin intact , then filling it with ground meat.
