Time for #WhatsItWednesday.

@cliffordbeshers no idea. Clearly a handle like pliers being held by a clip, but no clue what the rest of it is for.

@dejus I wouldn't have known either, until last week.

@cliffordbeshers It looks like some kind of mechanical “spreader” to widen fixed circumferences but I’m not familiar with it at all. Looking forward to this answer.

@gregmoore You are exactly right. It has a name and a specific material it operates on.

@cliffordbeshers The Mandalorian's new spaceship. 😍

@cliffordbeshers I’ll guess a plastic tube spreader for water lines.

@gregmoore This is correct, though it works on copper pipes as well. This is a swaging tool, which expands the end of a pipe so that the new inner diameter is just bigger than the original outer diameter. You can then join another pipe of equal size without any additional pieces.
