@DrOct I used to carry just one set, but as I kept getting more and more keys, I could never find the one I was looking for, so I had to switch to two sets, with the work set being 2 connected rings to help out some with the “finding the right key” part. My dad has about 4 sets, and he often is without the set he needs, so I can see the argument for/appeal of a single set (on the other hand, when he loses a set—always temporarily, thankfully—he only loses 1 of 4, so that’s the other trade-off ;-) ). // @macgenie @rosemaryorchard
