We had some contractors in the house recently. I noticed that one of them had a cordless drill with a tray holding the screws he was going to use. I asked him about it and he said that it was magnetic and held the screws until he needed them. The tip is also magnetic, so the screw he was putting in wouldn’t fall out. He also liked that there’s a bubble level on the top, so he knows if he’s putting the screw in right.
