I've yet to pick up some Tuf-Glide for myself (and after reading a thread about how well it lasts, I'm not so sure I ever will. Options are sometimes a good thing.)
My go-to pivot lubricants over the last few years have been RemOil (available practically anywhere, it seems) and Quantum Hot Sauce (an oil designed for fishing reels.) The only real problem I've ever run into with either of the above is that, unlike Tuf-Glide, they aren't dry-film lubricants, meaning they are more apt to collect dust and pocket lint. I am a bit hesitant to use them on knives that will see food use as well, as such, a good number of my knives go without.
For protection on carbon blades, I just use mineral oil... and very rarely at that. Living a mere 4 miles from the Gulf of Mexico, I have never had a problem with rust.
