5th Special Forces Group (ABN), Aluminum Guard, Mess Association SOG Knife that is attributed to a three tour veteran. The knife was retipped about 1/8 of an inch, shows honest wear and comes in the period leather sheath. The piece will come with about thirty original pictures taken during one of his tours (five or more of them showing the veteran wearing combat gear and tiger stripes the others are just misc pictures), his passport, a picture of him holding the knife when I purchased it and a letter of authenticity from specialforceshistory.com. The knife will be featured in my upcoming book on the SOG Knives of Vietnam. If you are looking for a real documented piece this would be it.
