I'm not interested in the who, I'm more interested in the why. Did the Kydex loosen up over time? Was the retention screw too loose? Did the...operator...not seat the knife firmly? Did heat play a role?

I'm kinda surprised it was Kydex to tell the truth. I suspected it was an old leather sheath that loosened up over time.
