Mmmm you gotta do the twist break, where you push sideways on the bottom part to see if you can snap off the entire clip piece, rather than having that shitty nub left.

But if you end up with the shitty nub by accident, you gotta bite that bitch off.

In college I bought myself a 50 pack of those cuz I lose shit a lot, and that clip never lasted more than a few hours on any new pencil…
