Unless you're trying to keep your EDC 1095 knife shiny-new looking all the time just carry and enjoy it. Rust is really no concern with regular use and carry. If you use the knife and carry it you'll have the natural patina of the steel and this is just nature taking it's course. Unless you leave it sit out in the weather for a couple days - then you might end up with some rust, but if you carry and use it daily (assuming you don't worry about normal patina) then these knives are very little maintenance. I really don't fret over them at all. I give it a quick wipe at the end of the day is about all. If using it for food I'll rinse the blade in hot water in the sink then dry the blade. That's it. A drop of oil in the joint once a month and it will last for decades.
Your bone scales are pretty much maintenance free other than maybe a wipe with thin coating of mineral oil a few times a year. If it's exposed to chemicals, etc that could be a different matter, but the natural oils in your hands alone will probably suffice to keep the bone scales looking good for many, many years. The only major enemy to any natural scale material is long exposure to direct sunlight (think dashboard of the car or a window sill?) and harsh chemicals.
If you put the knife away for a period of time is when I'd maybe consider a thin coat of mineral oil.
