The term 'GAUCHO's Tool' refers to two items used by the gauchos of South America, which are a REATA (a five-letter lasso) and a bola (a four-letter throwing weapon). The REATA is a long rope made of leather or rawhide that is used to capture animals or other objects. The bola is a throwing weapon consisting of two or more weights connected by a cord. It is used to capture animals or other objects by entangling them in the cord. Both the REATA and the bola are essential tools for the gauchos, who are South American cowboys.
