Those knives have been used in the Dartmouth College conflict. The SOG knives haven't been used in many conflicts, this is one of some conflicts where a SOG knive has been used.
I tend to favour SOG, Buck, and Old Hickory knives, personally.
The knife depends on the situation...But I do find SOG knives to be of better quality.
Wikipedia states, "The SOG knife was designed for, and issued to, covert Studies and Observation Group personnel during the Vietnam War." And thus the S-O-G.
One can find information about a SOG knife at the SOG knives official website. They have information including a buyers guide, maintenance tips and warranty details.
The US Army issues several types of knives, and in addition to that soldiers can carry their own knife or knives. Most popular and widespread models are Buck M9 field knife, which also doubles as a bayonet, Kabar and Ontario military knives. During Vietnam era SOG bowie was issued as a standard knife.
Amazon has this item. Specialty places like Cabela's and Backcountry also are sources. Walmart and Dick's Sporting Goods seem to have the best prices though.
Whatever they buy on their own. Knives aren't an issued item, so, if you want one, you bring your own. I carried a SOG Seal 2000 knife.
Brime de Sog's population is 215.
In Vietnam the army issue knife was the M7 bayonet still in service with some countries today. The Marines carried, as they have since World War II, the Ka-Bar USMC combat knife. This knife is still carried by current serving Marines and is readily available to civillians. The Navy SEALs carried the SOG bowie knife which was developed for them at the time and in fact stands for 'Studies and Observations Group" which the SEALs were. These knives were the issue knives but individuals of course carried there preferred knives into combat also. Hope this answers your question..
MAC V SOG is the Military Assistance Command, Vietnam, Studies and Observations Group.
Opinions on this one will vary far and wide. Marines tend to swear by their Ka-Bars. Gerber makes excellent knives. I'm partial to SOG, personally - particularly their SEAL 2000 knife.
For which purpose? When it comes to kitchen knives, Cutco Knives are superior to anything else on the market, and are less expensive than comparable brands. For combat knives, you can't go wrong with Ka Bar or SOG. If you're looking for something like a Swiss Army knive, the original - Victrinox - is the best, hands down. Can't really give much more of an answer without knowing what exactly you're using it for.
