Well I haven't been on this site for a while but last month you asked why the hog I harvested is called a razor back. The answer is somewhat conveluted. The more common name for this type of ferral hog is wild hog. The common name in USA is razorback. The wild boar is a direct descendent from the Eurasian wild boar. Believed to have been introduced to the Americas in the 16th century. It really is preference, some call it a boar, some call it a razorback.
