I didn't know that so I went and read about them. I could not find a single source that definitively states that "it's a tool for making fingers in knitted gloves."

That there are YouTube videos showing it being used to do exactly that does NOT mean that was its intended or original function.

In fact, all of the sources I consulted stated that your proposed function is one of approximately 50 possible and speculated uses but that there is still no conclusive evidence as to the device's original function.

Thus, I find your characterization of the article as "click bait" to be wide of the mark.
