In 1986, Spencer Frazer reproduced the original SOG Bowie knife to pay tribute to the Military Assistance Command Vietnam, Studies and Observations Group (MACV-SOG) that created it. What began as a single commemorative knife soon became a full line of innovative tools that are field-proven by U.S. Special Forces and even became the U.S. Navy SEAL’s “Knife of Choice.” Today SOG products are used for every day carry, by professionals or as outdoor essentials. What started out as “SOG SPECIALTIES” in 1986 changed to “SOG Specialty Knives and Tools” and is now “Studies and Observations Group.” SOG products are legendary worldwide for their uncompromising standards for quality, ability to perform in the toughest missions and incredible durability. If that’s not enough, SOG backs it up with a lifetime guarantee on all of their products.
