Abstract: A method for gripping such objects as tool bits and other implements is an extension of principles employed by tool holders currently in use, which grip at one (primary) position along the shank length. This invention provides auxiliary gripping, or what I hereinafter call "back up gripping" at one or more positions in addition to the primary gripping position. A universal tool holder or handle is presented as one embodiment of the invention. The holder is an elongated cylindrical sleeve one end of which contains a gripping mechanism utilizing back up gripping. The other end of the holder allows for insertion of a strike rod which, when making contact internally with the gripped tool, transmits to the tool the impact of hammer blows made against the outer end of the rod. The gripping mechanism of the embodiment is comprised of two pairs of traversely adjustable screws which serve as jaws or grips. Each pair of jaws grips the shank in an orientation different from the gripping by the other pair.
