Founded in 1986 in the United States, it is a veteran manufacturer of multi-tool pliers, and an enterprise dedicated to the manufacture of folding knives/multi-tool tools

SOG, originated from the name of a military secret special forces unit in the Vietnam War - Studies and Observation Group (reconnaissance group), this elite unit always carried out difficult and dangerous missions, known as the mysterious unit in the Vietnam War, is the secret operations unit of the US Marine Corps Special Forces SF Force.

The SOG combat knives were used for this elusive SOG special operations regiment, which at that time was made in Okinawa, a U.S. military base in Japan. Because this knife is more expensive and is a special knife for SOG members, in order to commemorate this unit, the company named it after the abbreviation of the unit "SOG".
