They’re all sawzalls to me. Fun bonus use: if you’re pouring a concrete slab, take out the blade and vibrate your forms. Edit: I’m not asking for a history lesson, I know who made the sawzall. I’m asking what term you use for it. Funny how many pencil necks don’t read the comments before commenting. If that’s the way you feel, upvote the first loser who came in here with that “actually Milwaukee…” instead of answering the question.
