With all due respect, who is throwing gratuitous rocks Jack? Let's compare ......
I believe the lister’s perception of "has seen considerable use" is far different from mine. And Jack, if that piece was carried in "Vietnam, and probably Laos and Cambodia", it was predominately at 10,000 feet in a flight suit or flight bag.
But I don’t usually just post fact-less or thoughtless opinions. I suggest you reread the obit........ well ... do you know the casualty rate among pilots in Vietnam?
I merely presented a case for the excellent condition of the knife and sheath, which one would presume precludes it from any real hard use or exposure to the elements by an Air Force veteran, hence my 10,000 ft statement. Yet I am attacked as you state I am posting "fact-less or thoughtless opinions". Wow. On top of that, you question my reading comprehension.
Lastly, you inexplicably throw the casualty rates of "pilots" in Viet Nam into the equation, and I am still trying to wrap my head around that one.
