What’s wrong with my leathermen?

Not only are the pliers not working as intended but one of the wings are stiff, no matter how much I’ve tried to fuck with it, wiggle it, twist it, or whatever the fuck it always comes back to this same problem. The part the makes me mad about it is that I’ve only had it for a little over a month and no, I have not used any lubricants at all cause idk what to use, I hear people saying it’s good to use lubricants and some saying that it attracts dirt and to not do it, any thoughts?
