Brian-There was a time, in the not so distant past, when there were no cordless drills (also, no computers, ipads, smart phones, twitter, face book, etc.) if you can believe that. So, as a young carpenter, you always had your hammer and awl, and if your were screwing things together all you needed to carry was a Irwin screw starter and you were set. Now about the old days, when dinosaurs wore nail aprons, if you were a young carpenter you could go to your local lumber yard ( no Home Depot or Lowes in these ancient times) and if you needed advise, guidance, your hand saw sharpened, etc., there were old retired carpenters working part time to help you. No bone head employee who wouldn't know his/her ass from their elbow. I sure miss those days!
