Today my favorite tool is my pin vice. It has many tiny drill bits stored inside and is just right for making small holes to start tiny screws in precious material. My youngest’s guitar needed a new tuning mechanism (a washer broke on the old one), and although the new part fit everywhere else, one hole was way off. Ten seconds with my pin vise and the last screw had a new pilot hole so I could smoothly screw it in. Now she can tune the guitar without the third string being squirrelly.
