Why no wet lube? Ive given mine a light lubricating with lubriplate 130a i think it was
Just my experience with the Yankee screwdrivers. Those are pretty prone to attracting dirt that makes them drag badly when wet. A Teflon heavy dry lube has worked best for me.
I don’t use my safety pliers often enough to have needed to re-lube them, but I’ll take a closer look at the mech when I’m back in the shop.
edit (6 years later): Sorry, I've been in the shop a few times since posting this, but haven't had the time to look these pliers over LOL, but after seeing that video below, I'm glad I didn't try taking mine apart. I'm still standing by my dry lube recommendation. Teflon is now passe, but good HBN options are even better. You absolutely could use a dry moly type lube on this, since the shaft is steel, but that can get messy, and being how these are often used in "clean" environments, do check into the acceptability of moly contamination before blindly taking my advice.
