OK.i use mine at least once a day.
If you do not need or use one, don't carry one.

Just ate a Big Mac and fries. Used the Soldier. If you don't use a sharp knife the salad squidges out everywhere, or at least that's what I tell people.

I have a SAK sat on my desk at work and no one gives it a second thought. It would probably raise a few eyebrows if there were any other kind of sharp knife sitting in it's place though.It doesn't frighten people. That's probably it's biggest selling point. If needs be you can use a SAK pretty much anywhere, even in these days of panic about knives, and people see it for what it is ... a tool for a job, and they don't become hysterical about someone carrying or using a knife.
I have never felt the need to. My oldest SAK is 15 years old, well used and is quite grubby inside now. But that hasn't affected the performance or smoothness of movement in any way.What do you lubricate your SAK with?
As HorseGuy says it might not need it, but I very often use my Officier Suisse for food and often wash it under the tap so it does need lubrication now and again. A tiny amount of very light oil (SWMBO's sewing machine oil in my case) is all it takes. Animal fats (e.g. from my skin and hair) would probably do it if I didn't have the Singer oil. I can't remember the last time I oiled the Soldier; I don't use that for food so often and then I usually just wash the blade without dunking the rest of it -- that's easier because it's a much bigger blade.What do you lubricate your SAK with?

No wonder it gets harder to open! Cooking oils are more heat transfer fluids than lubricants. Some will set solid if you leave them exposed to the atmosphere.... if I don't clean mine it gets harder to open. ... ... Sometimes I lubricate with cooking oil, ...
