Well, now I want a Fieldmaster! I was tempted to recommend the Huntsman, the only negative being the corkscrew (my preference, I realize YMMV). I wasn't aware of the Fieldmaster until now but I will have to make it my choice for "if you could have only one" since it is identical to the Huntsman except for the Phillips screwdriver. (I've had a Woodsman for over 40 years, a gift from my wife. She said she spent a long time looking over the various models and finally picked it. I think she did an excellent job. It is the same as the modern Huntsman but lacks the toothpick and tweezers. The saw and scissors are what really do it for me.)
