UBB.threads Forums Edged Weapons Miscellaneous Dagger Forum Boker RAD questions?

This is a photo of the upper fitting..The inside of the scabbard has the holes for the usual two screws. This upper fitting is secured by only one screw. This screw is lower on the scabbard fitting than usual. I am guessing this was maybe just a Boker manufacturing difference. Any input would be appreciated. Thank you.
