The SOG Bolo was sourced by Conrad B. (Ben) Baker of the Counter-Insurgency Support Office also known as CISO. Baker was named the Deputy Chief of CISO in June 1963. He also designed the famous SGO Bowie Knife. The Bolo was a shorter replacement for the US Isssue Machete and was based on traditional Asian designs, sometimes called a banana knife. The Bolo was often worn stuffed in the rucksack along the spine to protect the wearer.
