USN mk1 kabar factory error?

[Lucas P]

Hi all I’m new here, just picked up mk1 kabar online and when it showed up I noticed it has a weird grind. It appears it got flipped the wrong way in the sharpening process. The blade is sharpened on one side while the other is not ground. Interestingly the spine is also ground and tapered on one side making the blade extremely thin and bent. Any ideas as to whether this is original ww2 and value would be appreciated, I haven’t run into knives with factory errors like this.

Looks pretty weird but might be factory. There does look to be some cold bluing that has been applied though.

Welcome!  I'm glad you got my note.

 

One possibility is that the knife was one of those manufactured while training a new production worker. Another is that it simply didn't pass inspection and became a "lunchbox knife."

 

I have a "double-tang" Boker M-3 that shows several variations.  The metal was never blued or parked, the guard is on backward, and the leather-rings handle is still quite rough. I had another one with similar "defects".  Neither had the Ordnance "bomb" marking on them. Because both are "double-tang" M-3s, they were produced early on. That, plus the fact that I acquired two from the same person, led to my speculations.
