Abstract: A tool for connecting items to and from a split ring key holder. The tool includes a blade having a distal end opposite a proximal end with an intermediate portion therebetween. The distal end has a generally wedge shape with a narrow distal tip. The intermediate portion has first and second scalloped edges on opposite sides of the intermediate portion. The first and second scalloped edges define respective sequences of peaks and valleys opposed to one another. The narrow distal tip of the distal end of the blade and the first and second scalloped edges of the intermediate portion of the blade are adapted to separate and spread apart the split ring key holder. In the preferred embodiment, the blade is retractable and housed within a housing that provides for translation of the blade along a predetermined translation axis.
