SOG Specialty Knives

SOG Specialty Knives, Inc. (commonly known as SOG) is a U.S. knife and tool manufacturing company famous for their reproduction SOG Knife from the Vietnam era.

SOG currently manufactures a variety of knives other than the original military inspired designs, many designed for everyday carry (EDC). The company also produces a line of multi-tools.

The company was founded in 1986 by Spencer and Gloria Frazer and was inspired in its choice of name by the Joint Services Special Operations unit known as the Military Assistance Command, Vietnam Studies and Observations Group (MACV-SOG) who developed their own knife during the War in Vietnam.

Making changes to the original design of the MACV SOG Fighter, like resin-impregnating the leather handle, utilizing thicker stock and new grind lines, Spencer and Gloria launched their product and company with a one-page, black and white ad in Soldier of Fortune Magazine of the S1 Bowie, a replica of the SOG Knife used by the SOG groups operating in South-East Asia. They also produced the SCUBA/Demo knife, which is a replica of one of the rarest military knives to date (only 1 of the original 39 knives produced has survived till this day). Knives such as these and many of the SOG models produced prior to the shift of production from Seki, Japan to Taiwan are considered to be the best knives SOG had ever made.

A second "maritime" version of the Bowie (S2) was made utilizing a black micarta handle and stainless steel blade known as the Trident. It was decorated with the US Navy SEAL emblem as opposed to the Special Forces Crest found on the Bowie. The original S1 and S2 classic bowies were manufactured for SOG by Ichiro Hattori of Seki Japan until 2006. The other models were manufactured by Kinryu Corp. also of Seki until 2007.

SOG manufactures a knife used by the United States Navy SEALs dubbed the SEAL 2000. The SOG SEAL 2000 is a 7" bladed fixed blade knife with a rubber handle that was designed for the US Navy SEAL knife trials in 1992. The knife was manufactured from 1995 to 2007 for SOG by Kinryu of Seki Japan. Both the Seal 2000 and the smaller version, the Seal Pup are on display in the knife exhibit at the US Navy SEAL Museum in Ft.Pierce, Florida. Two SOG "Seal 2000" knives were used in the 2001 Dartmouth College murders. Scabbards left at the scene were crucial in tracing the killers.
