摘要：
A hand held tool for gathering and later releasing metallic particles such as paper clips or a spilled box of pins or tacks includes a handle with a magnetic attached at the bottom and a sweeper cover covering the magnet and hinged to the handle. Ferrous particles are gathered on the surface of the sweeper cover and later released by pivoting the magnet away from the cover.
