I just end up buying enough of the item to be within arms reach of nearly anywhere I'm likely to use it.
I used to never be able to find a screwdriver when I needed it, so now I have seven screwdrivers: three regular ratcheting, three stubby ratcheting, and a ratcheting one that lives in my pocket. I keep a regular ratcheting on my desk, in my living room, and in my bedroom, which are the only places I would realistically ever use these things.
As a result there's really no reason for me to lose it; it's already contained into the area that it already lives.
I do this with a lot of stuff now. Separate chargers for my laptop for my desk and my bed, separate iPhone chargers, and a bunch of other stuff.
