I used to stick my tools on the shelf and stick the empty plastic cases in the attic.

I bought a Festool saw that came in a systainer. I put the saw in the Systainer whenever it's not in my hands being used.
I sort of got into that kind of habit now with all my tools and really miss it when I buy something that doesn't have a hard plastic case.


It's not so much the tool, it's all the little attachments/pieces-parts/tools to work on the tool, that are now in one spot that I know where they are.
I don;t have to search high and low anymore for the allen wrench or the handle for the hammer drill or the stop guide for the hammer drill or the one and only 3/8" good masonry bit I own,,,,,or,,,,
