The Lopper Chain Saw

There are some really interesting chains. I'm not even sure what function this was for, but it like, had a pair of jaws at the end and with a little tiny chain saw inside of it. Counded like zeno morfh jaws. But i guess it did kind of look like this. Ah, but imagine i it also had a, like, a little chain saw inside its mouth. All i can think of now is like a sort of borg form of denturs where your teeth are replaced with tiny chain saws for enhanced chewing.
