Watched a video from razor emporium of them refurbishing a Gillette SS. They used mineral oil on the TTO mechanism. Mineral oil is food safe as well so there is less to worry about as with other oils.
My thought, thanks for clearing it up As Gary mentioned previously - 50 years ago - who counted on the razors to outlast man himself?
I used gun oil on my Aristocrat when the mechanism was getting sticky. Boiled it twice with some dish soap (this was Rhodium so I didn't need to worry about the finish), and one drop down the barrel, moved the TTO about 20 times and it's been smooth as silk for the last few months. I would have used mineral oil but whatever, didn't have any at home - my oil is a skin irritant normally but I washed everything off the external surfaces and haven't had any spillage from within the mechanism.
No place. I just oil my razors because I choose to. I've never read anywhere that you have to oil your razor.
I don't believe the no lubrication thing because in a 60 year old Fatboy there is how much goop in that mechanism? Not tons but enough that it will become noticeable over time; they may have designed it to work without lube but let's consider the fact that they didn't expect someone to use the same razor for 50+ years either.
