KVD Shark tooth... Anyone use one of these?

[Can't Catch Bass]

Hi all. I just stumbled across this little gadget and I was surprised I hadn't heard of it before. Does anyone have experience with it?

I noticed that the video was from 2011. I wonder if it is even available now?

Never seen this.....

 

You can make something like this with two rubber bands and a wacky ring.

Looks like Maxima got tired of cutting checks to KVD.
