I'm a big fan of Hondas moly grease for use in my ratchets, bit pricey but it makes them so much smoother. Krytox is a true super lube and they do have a grease that works well in ratchets but is is very hard to come by and has a pretty steep price tag, and in my opinion is not noticably better than Hondas grease in a hand tool application, that is unless you plan on using your tools in an extreme environment like outer space, or under water where the Krytoxs thermal stability and solvent resistance will have a distinct advantage.
