Some years ago in the Ardennes at a 17th Airborne weekend.
In a barn a young re-enactor is using the flat side of his fighting knife to tighten on his shoe laces (no idea why).
My friend and I look at each other thinking or saying he will hurt himself.
At that moment the knife slips from his laces shooting up into his face to his eye.
He actually cut the outside of his eyelid drawing a single drop of blood. Luckily nothing more.
It scared the excrement out oo everybody who saw it...
I am sure he will never do that again.
My brothers M201 had something similar. From memory...It ran until the batterys were discharged after first loosing headlamps.
It wasn't charging. I think it was the regulator? The rectangular electricity box of magic tricks...
