It could be embellished by adding a penny and a dime.

The 2000 amp wrench reminds me of an incident that I had at work many years ago.  I was assigned to

troubleshoot and repair a battery charger.   This charger was supplied by 480 volt 3 phase power.

The battery was 48 volts and as big as a large desk.  The battery powered an electric hi-lo.

I locked out the 480 volt supply but never thought about unplugging the remote "dead" battery.

Even discharged batteries have some stored energy.  My wrench shorted out between the bolt holding

a large diode and a heatsink.  And the wrench welded itself in place.  That is when I realized the remote

battery was plugged in.  As I walked away, the wrench turned red hot.  At 6 feet away,

the wrench turned white hot and melted in half.  The whole incident lasted about 5 seconds or so.

Is that considered slow blow?
