This is a very special piece, an original ATAK that was made for and was carried by a Navy Seal. On the blade it is stamped "CNSWG-1" "163", which stands for Commander Naval Special Warfare Group #1. The black coating on the blade is coming off, there are some scratches visible and the handle has some dings, again the knife was carried by a Navy Seal. Includes a black kydex sheath. This is the second of these that we have had, very special and rare. This knife was issued to and carried by a Master Chief Petty Officer (SEAL) in the mid 1990's when he was assigned to SEAL Team 5. Comes with a letter to AZCK from him including his contact info that he will include to the purchaser.
