Abstract
An elongated preferably plastic handle has a sleeve lock on the tip end. When a twisted wire brush is placed in the handle, there is a guy wire effect from the sleeve which holds the brush firmly in place, as the sleeve stretches slightly over a bent end of the twisted wire of the brush. The inventive handle also holds the end of a wooden toothpick, which may be broken without leaving any exposed jagged fibers which could form splinters.
