You're mid-solder on a small IC or a transistor lead and the heat is creeping into the junction you don't want to cook. Or you've got a 0402 resistor balancing on its end and your fingers are in the way of the iron. This little tool does both jobs. Clamp it across the leads to wick heat away while you work, or use the jaws to hold the component steady so your hands stay clear. Insulated handles mean you can grip it without worrying about the metal getting warm. Small, cheap, and it saves components that would otherwise end up in the bin. Keep one on the bench. You'll wonder how you went without
