Abstract
A plier for inserting and removing retaining rings and other purposes. The plier is convertible for alternately closing and opening of the jaws as the handles are closed. The handles and jaws are rotatable about a pivot shaft. Cams effect movement of the key members between a first position wherein a first key member connects a first handle to a first jaw and a second key member connects a second handle to a first jaw whereby the jaws move inwardly as the handles move inwardly and a second position wherein the first key member connects the first handle to the second jaw and the second key member connects the second handle to the first jaw whereby the jaws move outwardly as the handles are moved inwardly. The plier includes a storage cavity for tips and tip change tools.
