These are hand devices intended for recovering little ferrous parts from challenging to-arrive at areas. They are ideal for recovering washers, nuts, and bolts from awkward places because they extend up to a certain length. A few models accompany extra elements like a Drove light in the head for better perceivability in dim regions. The holding force of these apparatuses can go from 2 lbs to 6 lbs, contingent upon the model. They are ordinarily made of hardened steel for toughness and element a finished elastic handle for added hold. Most models utilize standard batteries and can be initiated by curving the neckline of the head.
