For your pocket knife destruction pleasure:
I’ve turned the front end of leather man longnosed combination tool into plasma.
Clue: lots of very large lead acids in a long bank.
Had been told the charging leads where disconnected at the battery end...
tiz funny now, “bright light!” LoL.
Still hate any form of unnecessary cable clamping or tieing to this day.
The cutters at the back of the jaw survived, still use them.
My most impressive bit of arcery involved a piece of equipment that had had four different sources of power feeding it.
I had forgotten about the control voltages that came down from the office level. I survived. My tool, like yours, bore the mark.
Never told anybody, for some reason.
