An ice screw includes a hollow tubular shaft with external screw threads formed on the shaft and a hanger attached to the shaft. The hanger has an eye for clipping on a carabiner. A foldable handle is pivotally attached to the hanger to pivot between a crank position and a folded position. In the crank position, the handle extends from the hanger for grasping to rotate and thus rotate the shaft. In the folded position, the handle folds into a recess formed in the hanger. In the crank position, the hanger serves as a lever arm or crank arm for the handle.
