A Question:
What does disassembling your knife (or knives) do to the warranty?
I've read here at BF that taking apart most brands of knives voids/murders the warranty. Even the one (Benchmade?) that includes the tools to take it apart, says the warranty is void if you take it apart.
Just because it can be taken apart, don't mean it should be.
A lot of knives have screw construction, and the manufacturer used red (permanent "never" come apart) lock-tite on the screws, rather than the it's possible to take it apart blue lock-tite.
Look at how many threads there are with the "I took my _(brand/model)_ knife apart, and now it don't flip/I can't get the blade centered/ I have stripped/broken or missing screws, or some other problem, or I can't put together ..." theme on BF and other knife forums.
In 60 plus years, I've never needed to take apart a knife to clean or lube it. Hot running water or swishing in hot soapy water, then rinsing in warm/hot water, and drying with compressed air, and a drop or two of lube in /on the joints is all it takes to clean and lube a knife. A drop or two on the joints and open/close a couple times is all it takes to lube one.
If you're going for "sterile", forget it. Nothing that is exposed to the atmosphere is "sterile". The atmosphere at a minimum has bacteria, viruses, dust, mold spores, and pollen. A "Sterile" item is a myth, outside a pressurized "clean room" at a laboratory.
Remember: Some microbes can survive exposure to alcohol, acids, high salt concentrations, heat, cold, radiation, vacuum, and UV rays. The "best" hand sterilizers/hand cleaners only kill "up to 99.9% of germs"; not "100%". Hospitals are breeding grounds for "super viruses" that are immune to the cleaning solutions used, because they didn't kill all the germs when cleaning. Even the so called "clean rooms" have some contaminants/"germs"/ bacteria/viruses in them.
