It's a saw! They're sometimes used as a musical instrument in American folk music. This originated in a poor area where people had limited access to conventional instruments, but somebody figured out that you could get an interesting sound from a hand saw. https://www.musicalsaws.com/aboutus/

I won't be able to look at sheep now without headbanging to dirty deeds... Thx a lot!!

Do you have a lot of sheep where you are? They're a rare commodity out here.

I don't see any problem with headbanging at the sight of sheep. Some of the sheep might be headbangers too. Or maybe they're goats.

Speaking of headbanging...

I do think both are sheep.

And I love the headbanging bird!! Too bad it's a short video...

Another rockin' cockatoo. The birds in the background aren't into it.
