I spent a lot of time organizing my tool box....to no avail. I am terrible about putting tools back in their place, and opening every drawer to see what is missing is usually hopeless.
I am planning to use my double decker tool box for only loose stuff, like sockets, allen wrenches etc, and I am going to mount a large 8'x12' section of peg board on the garage wall and mount all the wrenches, pliers etc etc on it and outline them (kinda hokey old school). That way I can see at a glance what is not put away.....
When I am in the middle of a project, I usually have all the tools I have used that day on a table in the driveway. At the end of the day, I am too tired (er,,,lazy) to put them in the tool box, so they end up piled into my toolbag.
......the worst part is, I get soooo pissed when I spend 20 minutes walking around like a fart in the wind looking for a tool.....oh well....
