Claim 17:
18. A method for driving a cylindrical shaft within a material using the apparatus of claim 2, comprising:
inserting the cylindrical shaft into the opening at the distal end of the housing;
pushing the cylindrical shaft into the space defined by the at least two first cylindrically symmetric gripping members and the at least two second cylindrically symmetric gripping members; and
after inserting the cylindrical shaft, either:
rotating the housing in a first direction so as to cause the at least two first cylindrically symmetric gripping members to move toward the second end of the corresponding asymmetric cam surface, thereby gripping the cylindrical shaft and rotating the cylindrical shaft in the first direction; or
rotating the housing in a second direction so as to cause the at least two second cylindrically symmetric gripping members to move toward the first end of the corresponding asymmetric cam surface, thereby gripping the cylindrical shaft and rotating the cylindrical shaft in the second direction.
