Unless it’s H1, it requires cleaning after use before putting back in sheath. In urban/office environment this is hard to do. This situation is where H1 folders or very stainless blade folder is easier, just fold away and store until cleaning is possible. Example: cutting fruits or cakes or sandwiches (with all the ingredients).
One of the reason I used to like balisongs. No touching the blade at all and if well made, no rubbing the handle except kick and tang pins. Can clean up just the blade later if needed.
For fixed blade, how do you all get around clean/dry/store cycle? How about cruds in the sheath?
I hope it doesn’t derail the thread and provides insights to non carriers like me.

Personally I never close a knife while it's dirty if I can help it. Cleaning a blade is easy. Taking apart a knife to scrub rust off the liners and pivot is not!
Simply wipe it off. I cut apples with my Ronin 2 every week, often while camping. I squirt a little water on the blade from my water bottle and wipe it off on my pant leg and it's fine. Nothing to it.
I can't think of any reason to not wipe off a knife before putting it back in my sheath / pocket unless it's an emergency or something. I have a tough enough time avoiding rust as it is.
