    That tool is a winner for some one who does that for a living. That is 10 times faster than a pair of Malco crimpers. The hand crimpers have their place for the casual user, but this is what a tinner needs on the job. Excellent!

    That, or possibly a pair of dies, driven by a rotary cam (?)

    Cams make sense. The gears must back away to allow the metal to enter

    Seems to have no eccentrics, a mere 2 gears (with tapered ends?) and loose fit is rugged and "field expedient" enough,
    as the manufacturer's own instruction tells you to enter/ exit at an angle:

    Ah, now I understand. The key is that you enter and exit at an angle. I didn't see that part of the process in the video.
