Just a thought....
There was a large butcher knife on the Mil forum a few years ago.
Certainly didn't look military but it was marked as such.
Seems it was meant for butchering animals "foraged" in the field.
Multi-purpose. After all, soldiers can't carry a bunch of specialist knives in the field.
Not suggesting this one is military...
If you want to win an argument, it is best to stick to the truth.....or,at least, provable untruths.
