I have a very large tool chest that is well stocked with mostly Craftsman tools. In addition, I have a set of Stanley 3/8 drive sockets that I bought about 25 years ago (before I had any other good tools). The set is in a blow molded case (about 5"x 9") and includes metric sockets that are 6 point (from 10 to 19mm) and SAE sockets that are 12 point (makes it real easy to identify them). This set goes with me under the car for most any job. I also have a set of combination wrenches in a plastic 'sloted' holder that is easy to take to the job.

Other than these, I go to the tool chest and get what ever else I need.
