 The BSA introduced its own square knot insignia in lieu of the military-style ribbons in 1947.The choice of the square knot as the common emblem was made by James E. West, who is said to have chosen it for its use as the knot associated with first aid, thereby reminding Scouts to continue to be of service to others.The first eight awards with square knot insignia in the BSA were the Eagle Scout Award, Quartermaster Award, Scouter's Training Award, Scouter's Key, Silver Beaver Award, Silver Antelope Award, Silver Buffalo Award, and Honor Medal.
