Your free repair tools are waiting for you at your family dentist.
Many dental instruments are double-ended, and if one end breaks,
the instrument is considered worthless. If an instrument is a little
rusty or has just fallen out of favor with the doc, it is just taking
up space in his office. My dentist had DRAWERS full of this stuff and
he was more than happy to get it out of his office. (Hemostats make
great heat sinks and hold small items, other instruments can get into
all kinds of nooks and crannies.) I encourage you to place them into
autoclave bags and get them sterilized before you leave the office.
