Is that an LED under the head? Could come in handy if you needed to
drive a nail in the dark.

Maybe it's a laser - so you can see if you're going to hit your finger
and/or
thumb.

Couid be an infra red detector that sense the heat from your finger
and/or
thumb. If it detects a warm finger and/or thumb in the path of the
head.
a customizable program for the built in micro processor will release the
patent pending "hammer head lock" allowing the head to pivot back on the
hidden hinge below the claw end of the head, I wonder if you have to
return
it to the manufacturer to have the "hammer head lock" reset - or
replaced.\

On thirtieth thought - could be an electrically heated hammer handle.
If
you've ever had to do any hammer outside during the winter - in
Minnesota
- you know that when your hands are REALLY - though not cold enough to
go numb - it REALLY hurts - more than if your hand was warmer.
