ABSTRACT:
A curling iron which has a handle, a barrel extending axially from the handle, a heater for the barrel, a spring-pressed, pivoted spoon for holding hair against the barrel, a spoon extension formed as part of and extending outwardly from the spoon, proximate to the handle, and a thumb button at the end of the spoon extension. At least the outer surfaces of the spoon extension and the thumb button are covered with a thermally-insulating plastic material, so that these surfaces are no longer hot to the touch. The inner surfaces are preferably not insulated; this permits heat conducted from the spoon to the extension to be harmlessly radiated away inwardly.
