Designed in the shape of a pencil with pocket clip and small magnet at the tip. A spring wire clip is located at the middle. When the "pencil" is held by this wire clip, the "pencil" pivots on this centerholder as the magnet is attracted to magnetic minerals present in a rock specimen. It is good to use in a pan to separate magnetic particles from gold. Length 12 cms (4-3/4 inches).
