2 concerns I have about it are --
1- the lack of a hook straightening hole in the pommel end bolster - every other Kabar folding fish knife I can remember seeing has a hole in the mark side of the pommel end bolster
2 - the deeply stamped KABAR on the blade way out under the nail nick. I have never seen one stamped like that before.
I'm more of a fixed blade guy than folder guru so I readily admit there's a ton of Kabar stuff I don't know, re: folders, but these two items raise a red flag in my mind.
