Clackers or… death on a string came out in the 1960s. They were also called Ker-Bangers, Klackers, Click-Clacks, Klik Klaks, Klappers, and Zonkers.
I remember a kid giving me his Clackers. The object I guess was swinging them up and down until they hit each other and made a “clack” sound. The sound I got the most was a thud sound with plastic hitting my skin. They were also known to shatter and the pieces fly in all different directions.
They were similar to Bolas…a weapon used by cowboys to throw at cattle or game to wrap around their legs…sometimes breaking them. Yep…lets redesign this and give it to kids.
I never minded somewhat dangerous toys but I didn’t get too much pleasure out of these.
The toy was recalled in 1985

You don’t know how close I came at doing a post on my blog about these. The object was making them hit over your hand and under. I could do it for a few seconds but I always ended up with a bruised arm and hand.

I had some, when I was a kid.
I also had a set of lawn dart and a slip-n-slide.
Some if us were indeed bruised and broken, still… we survived.
