I was active duty AF for 8 years, spent 6 months in Desert shield/storm. I owned both the pilot survival and the Issue F/U. First of all as to whether you can carry this knife, it is usually dictated by what job (afsc, mos in your in the army, etc.) that you have. Second it is dictated by your unit commander, regulations, etc. For mine it was a 3 inch blade, in war the rules go out the window! Then the truth is what are you going to use it for? a pilot survival knife is okay for a pilot, but for actual survival you would be better off with a F/U or a SAK. The teeth (saw) on the pilot's knife are great for cutting the airframe (thats what it is made for), but poor on wood. A F/U although not a strong as most production knives is till quite serveable for most all purposes. I carried one for the time that I was in and it served me just find. The Pilots knife has a nasty weak point at the hilt and could snap off. Now granted it does take alittle to break it, but Ive done it. Ive also seen others break them, usually by throwing, but also from cutting/chopping tasks. I worked in survival equipment for 8 years and the survival knives we used were either the old 4 blade metal utilities, or the small 3 blade colonials. The only other knives were the old floating curved blade (for cutting lines in a life raft) and the curved knife for shroud lines (parachute lines). Personally I would use a F/U. You will find that most, not all, of the pilot's knives that survive have not seen much survival/utility use. What works really well is a SAK. As far as leather handles and jungle rot? yes it does happen, but you can soak a leather handle in parafin wax and it will definitely make it last longer. The one thing you will find is most do not like to carry a fancy knife. Its best to use an inexpensive, but effective one and replace it if need be. Experience is the best teacher, although its better if you gain some knowledge going in.
