I have this curse of "out of the house" pants, "in the shop" pants, and "lazy" pants so I am really bad. The dumbest was my Zippo but the most common are the little folding utility knives. I tend to drop them in a pocket and... they're gone.
The knives just need a quick dry and oil but boy does one feel like a fool drying, refilling, and replacing the flint on a Zippo that got the laundry treatment.
