A split resilient ring has a pair of converging implement socketing sleeves anchored thereto and adapted to receive various implements whose work-engaging terminals may extend substantially outwardly of one or both corresponding ends of the socketing sleeves. The work-engaging implement terminals can be biased apart or together by the holder for a variety of useful operations. In lieu of the split resilient ring, a wedge fulcrum member may engage converging or diverging implements biased by elastic elements.
