There is a particular kind of purchase that households make repeatedly: the tool you are fairly sure you own, cannot locate, and need in the next twenty minutes. Everybody has three tape measures for this reason.
Two different failures
One is storage — it is in the house, in a box, in a place nobody has designated. The other is lending, where it left months ago and the memory of who took it went with it. They feel the same in the moment and need different fixes.
Write down the location, not the object
A list of tools you own is much less useful than a note of where the uncommon ones live. Nobody loses a hammer. People lose the pipe wrench, the stud finder, the socket set, the thing bought for one job three years ago — and for those, one line saying which shelf beats any amount of tidying.
