First it's worth pointing out that thare was no one single type of "Vietnam fighting knife" as such. Various units were issued various types of knives, depending on their missions. These included the standard M-7 bayonet. What you are probably referring to is the Air Force survival knife, which was also issued to personnel in other military services. (I'm far from being an expert on military knives, but I did tote one of these for the eight months that I served in Vietnam, 1969-1970 -- even though I was in the Army.) The survival knife is indeed intended as much as a multi-purpose tool as a weapon. One example of this is the hexagonal butt that can be used for hammering (or smashing through things, such as a plexi- glass canopy). Another is the serration on the back for heavy-duty cutting. As far as I know this knife is still in use today -- and you can buy it from many of the companies that sell military-related items. Though the only thing I ever used my survival knife for was cutting of food when no other appropriate cutlery was available, I did spend a good deal of time flying on both large and small aircraft of many types. In several cases, the pilot and I were the only ones aboard, giving me a chance to talk. (Also, as part of my job writing up daily action reports -- mentioned in an earlier posting on equipment reliability -- I had access to field reports which described how and why aircraft went down.) There were a couple of things that became very clear to me from these sources. One of these was that fire was the biggest threat in a crash landing. Another was that in some cases the buckles on the seat/ shoulder harnesses locked up on impact, and that you might have to cut yourself free. For that reason many of the helicopter and small fixed- wing aircraft pilots and crewmen that I knew wore their survival knives strapped to their legs. If you are belted in, and the knife is on your belt, it's under the seat-belt harness and hard to get at when you need to cut yourself loose. As far as getting out of a downed aircraft -- it's important to remember that much of the exterior skin of small aircraft such as light helicopters is VERY thin sheet metal. That skin is for aerodynamics only. Larger aircraft with pressurized cabins are a quite different story. You'd spend a lot of time trying to saw through that type of metal with any kind of hand tool. The threat of fire (burning, and not in the sense of "enemy fire") was also the main reason that almost all the aircraft crew members I knew would not wear the canvas-side jungle boot but rather opted for all-leather boots which gave better protection in such a situation. -- Ernest My opinions are my own and probably not IBM-compatible.--ehr Ernest H.
