Yeah, electricians seem to delight in burying the wirenut in insulation
tape. It looks very good going in, but a year down the road the
insulation has welded itself and won't unravel. There you are jerking
the thing around and using the knife in close proximity to other hot
wires.

You can grab the whole strip with hot connections while you tighten new
ones,
and you're insulated all the time.

Except for the screw driver shank.
