Etymology
The term 'jackknife' originated in the 19th century, referring to a type of folding knife that opens and closes with a pivot. The word 'jack' in this context is thought to relate to the name 'jack', commonly used to denote a man or a common man. The 'knife' part refers to the blade's action of folding in on itself. In the context of vehicles, the term evolved in the mid-20th century when large trucks began to be more widely used. The visual similarity between the folding action of a jackknife and the way a trailer can swing back toward the cab of a truck during an upset led to the adoption of this term in the transportation industry.
