I find it interesting to look at a subject from two different points of view, sometimes. In this thread we've looked at the pilot survival knife from a "knife" aficionado's point of view, and as such, discovered limitations in it as a knife. It has rather unsophisticated steel, little asthetic value, and an inexpensive price (connoting lower quality). Now let's change points of view. Having been involved in military R&D (materiel acquisition) before I can tell you that the purchase of this knife was driven by a mission, a need requiring a solution. It probably went something like this: "Statement of Need: There is a requirement for a device/tool to enable downed aviators to extract themselves from their aircraft and survive on the battlefield until rescued. This device must accomplish the following tasks: (1) Pry open canopies. (2) cut plexiglas. (3) Perform as a survival knife. (4) perform the functions of a hammer....etc. It must have the following characteristics: (1) Be no longer than 10 inches. (2) Have a blade no longer than 5 inches. (3) Be non-reflective. (4) Have a rust inhibiting coating. (5) Weigh no more than X ounces. (6) Be sharpened in the field by using available sharpening systems.....etc."
What comes out of the above statements is something to fulfill the need. It may look like a knife, or it may look like a sharpened shovel or prybar depending on the priority given to the requirements. In this case, it looked like a knife. But in the military's point of view, it is a "tool" that happens to resemble a knife and meets the criteria (whatever it was way back then).
So when we look at military knives as knives, they usually don't measure up to our expectations, but when we look at them as tools to fill a need (and made by the least cost producer at the time), they look differently.
Just my perspective from having done this before (although not for knives).
