Oiling Slip Joints?

I use my knife for food also, so mineral oil. I only oil it as needed, when it gets sticky. I just dunk the pivot end in a bit of mineral oil in a shot glass and leave it while I do something else. Maybe a minute, maybe overnight (usually just a minute). When I get back to it, I grab a paper towel or linen kitchen towel and work it back and forth a bit (it's deadly sharp, so you need something to protect yourself, pinch the blade, stay away from the edge). Then I wipe the oil all over the knife (the oil gets all over anyway). Usually is good to go after a few cycles. Wipe off the extra oil. Takes longer to type this than to do it.
 
Honestly I have been through so many oils. My father is even a lubrication specialist and he has given me a ton of options otherwise unavailable to the general public. Finally I tried nano-oil and at first I was very skeptical. The stuff is the best I have tried.

I soaked a old TL-29 in mineral oil. It made the old wood scales swell and become loose.

I have soaked very old wooden scaled knives in Mineral oil- and never had a problem. These have been Ebony also rosewood- all sorts. What could have happened is the rust I between the wooden scales and Liners may have come loose from the soaking? Who knows.
 
Toothbrush damp with mineral oil or baby oil

Open the slip joint half way and brush
then the whole way and brush

Wipe oil on to the blade
Close the knife a
Buff in the slight amount of mineral oil into the scales

Thanks for correction, Jerry - I didn´t find the correct words :rolleyes:

You are right, it´s not aggressive but it will corode brass liners over time. I use Ballistol for everything around the house, for being the best oil around - except my beloved Traditionals. I made a bad experience in the past on an Hartkopf knife with brass liners that got very bad while using Ballistol for over some time.

Thanks Pappa Andi :) good to know that. I've not used much of it at all. Mostly for my fixed blades in carbon steel. I found out many years ago that some seemingly harmless gun products could be destructive over long periods of time, but most all of my slipjoints have SS liners. I also use Eezox and RemOil but never on natural cover or handle material. For them I use Howard's Feed n' Wax (mostly bees wax).
 
I use mineral oil on anything I would use on food. I use 10wt Nano oil on all others (on the joints). Aero-kroil is also a choice on knives that will not touch food.
