Looks nice what era is it from?1963 up?
All I have found about this blade is it was an "issue" item from about 1962 - 1967. Seems it was reserved for meritous duty/achievement and or retirement as a green beret. That's all I know and would love to know more.
I agree with that hate to say it but I used to throw my uncles in a tree in my back yard I was good with it too wish I still had it I remember it like yesterday. Yes im one of those dumm A.. Kids
