Two incredibly handy tools seldom used for their intended uses are dental mirrors (a.k.a. "inspection" mirrors) and dental picks. The one problem with most inspection mirrors is that when you have to look into awkward electronic or mechanical crevices where you need a mirror, you also need a flashlight for illumination and a spare hand to hold the light. This kit (#832) has a dental mirror with a bright flashlight integrated into the handle and a switch in the grip, freeing up your other hand. The other neat thing is that for less than $10 you get two dental picks -- great for nudging or extracting small inaccessible components from assemblies. Recently, I was upgrading a friend's computer. The motherboard was mounted in a "baby ATX" case which was a very tight fit. To locate the CMOS reset jumper or check to see if the memory socket catch was engaged, I needed the use of the lighted mirror to negotiate the dark spots where those components were hidden. In the same manner the picks were handy to snag small cables within the case.
