I had to vote 5-7.
* I have a rool-away chest-on-chest topped with a tool box out in the garage for automotive use.
* I have a portable tool box for auto and trailer/camping use on road trips.
* I have a portable toolbox for my bike tools.
* I have a portable tool box in the basement shop for those household tools that aren't hanging on the pegboard (I never, ever use automotive designated tools indoors).
* I have a fanny pack stuffed with bike tools that I stow on my bike for emergency road use (the cell is useless now as the bride no longer drives).
