How do I plug this in? Old Black & Decker Hedge Trimmer. - eviltoast

I acquired this older Black & Decker Hedge trimmer and it seems to have a special kind of cord. Any idea where I could find this cord or what its called? I have not been able to even figure out what the cord looks like yet.

UPDATE: I cut off the extra plastic to get access to plug it in and the tool doesn’t even work anyways. Time for the garbage.
