examples.
box of epic proportion fail. too many huge tall drawers.. narrow too! it ends up taking up a lot of space and really not storing any tools. its a 2/3rd split too, so the drawers on the left end up being too narrow to hold large tools or really be useful.. then its the standard cheap 18 inch deep, so your tools cant be sorted well. it *looks* like it has a lot of storage, it takes up a ton of room, and it really wont hold or organize anything well. avoid this style like the plague.
we dont all have that many tools.. some of us do need a smaller box.. get something like this
much better use of space. has a flat top to work on. none of the drawers are too tall either. this will maximize organization and utilize maximum space of the box. a small box, but effective and useful, minimum waste and clutter. still a shallow 18 inch deep box, but better than the first, more common example.
the ideal box. ~30 inches deep, big top work surface.. that top full width drawer will be your workhorse for sockets and common tools. fantastic organization. you'd be amazed how much quicker you can finish projects when you're not spending half your life searching for tools. this type of box takes advantage of your real estate the best, and ultimately is what everyone whos serious about tools ends up owning, for good reason.
