Oh yeah. That one he's talking about is usually coupled with a magnifying glass to help electronics designers and hobbyists work with printed circuit boards. Usually you need at least three hands, often four, to get parts soldered together and this holds the board in place nicely. The alligator clips are pretty toothy and stiff, so you probably would need some bit of cover.
Find them at any electronics hobbyist store or site (Amazon, Sparkfun, Digikey, probably Element14, or Adafruit).
