What is this tool called?

I think this looks so interesting and simple but besides this one video, I can't find anymore information about it. When I look up reel and stick I just keep getting fishing reels.

It would be called a reel until about 5 years ago. As in silk reel, yarn reel (sometimes called a skeiner if used to make skeins, blocker).  The Big Book of handspinning goes into this tools variations in some detail.

I use the larger version for yarn blocking here.  (Chapters are in the description so you jump to blocking)



The skeiner or click reel should be in this video too.  It's a newer version (1800s) of the reel you show in the video)  oops.  Different video.

Now the words are changing meaning. Anything that holds yarn is called a swift, apparently,  no matter its function (swift is a very different tool, but it might help with google)

Old style, name follows function
New style, everything is a swift now.

Maybe this YouTube could help? I think it's in Portuguese? The subtitles to English mostly make sense.
