  • Patent number: 5829111
    Abstract: A pliers-like hand tool is provided for removing plastic grommets or other similar insert members embedded within concrete during a post tensioning or other forming process of concrete construction. The hand tool includes two hand members each having a jaw end portion, handle end portion and intermediate neck portion, being pivotally connected between the neck portion in a well known structure for gripping a workpiece between the jaws. A fulcrum protrusion is formed with the tool at a point near the jaw end and acts to provide a bearing on the concrete for a leverage action which is caused by pressure being applied to the handle ends against the concrete in order to extract the grommet which has been gripped between the jaws of the tool. It makes the removal of grommets easier in a labour-and-time-saving way. It is also helpful to preserve the grommets for future re-use.
