I am joining this "can't find it & possible solutions" discussion late.
Here's my contribution.

My dad used to get really upset because he could never find a 9/16" wrench.
We would spend hours hunting that thing down. When I grew up and flew the
coop, I ended up at an industrial surplus place that had numerous wrenches
in a scrap bin. I fished out a goodly number of various sizes and a whole
bunch of 9/16" wrenches.

I sent the wrenches to him. He got upset at me. But years later, he thanked
me. He said he never knew how a bunch of 9/16" wrenches could come in so
handy!

As for me, I never could keep track of a measuring tape. I had to keep
buying new ones. I had several, but the just vanished all the time. Then
one day at the industrial surplus center, just love that place, they had a
sale on a big batch of tools. And on the shelf, they had a number of bright,
neon colored measuring tapes.

I bought all 14 of them. And I have bought more over the years as well. My
wife even bought me that giant battery operated meauring tape from Black and
Decker! I have several measuring tapes in my office, a couple in the living
room, one in each car and a couple in the wife's sewing room. And lots of
them in the shop as well. I am never more than a few steps from a measuring
tape.

I wish I could tell you that solved my vanishing tools problem. I still have
that malady. But as far as measuring tapes go, I am covered.
