That, sir, is a WWII folding pilot survival knife. Very nice.
...(side note: it has a 90 degree stopping point just like the slotted driver/bottle opener on a victorinox, which I find very funny because the saw couldn't possibly be used well in that position) ...
Congratulations on becoming a custodian on this heirloom! And for sharing it with us.
So why exactly were they folding pilots in WW2? Were the planes so small?
I think I saw one of those in a video by [the guy who eats old military rations on youtube] in a video about pilot survival kit.
A very intreresting knife and backstory for sure. Was your great grandfather a navy pilot?
...Just to reiterate, I am really happy to get this knife. About a year or two ago, the same Uncle forgot to empty his pockets and bag before rushing to catch a flight and ended up getting 9 pocket knives taken by the TSA! My Aunt tells the story about being so embarrassed that they kept finding more knives like it was a comedy sketch. Needless to say, I am very glad that this was NOT one of the knives he was carrying that day.
