Abstract
A telescoping rotatable tool includes a first shaft and a second shaft. The first shaft has a first material-engaging element extending from an exterior surface of the first shaft. The second shaft has a second material-engaging element extending from an exterior surface of the second shaft. The second shaft is configured to extend from and retract within an interior space presented by the first shaft. The first shaft includes at least one helical-shaped groove extending along an interior surface of the first shaft. The second shaft includes at least one guide element extending from the exterior surface of the second shaft. The guide element is configured to engage with the groove, such that as the second shaft extends from and retracts within the first shaft, the second shaft is configured to rotate with respect to the first shaft.
