ABSTRACT:
A magnetic pickup tool including a length of highly flexible tubing with a permanent magnet secured to one end of the tubing. Removably positioned within the interior of the flexible tube is a stiffening member such as a length of iron wire of about the same length as the flexible tubing. The stiffening member is bendable but when bent has the ability to take a "set". A second length of flexible tubing completely surrounds the first or inner tubing and is slidable thereon. The function of the outer tube is to surround the magnetic tip when the tool is in the process of being positioned to pick up an object so as to prevent the magnetic tip of the tool from being attracted to an unwanted metal object. After the tool has been positioned at or near the object to be picked up, the user then grasps the outer tube and pulls it away from the magnetic tip exposing the tip to make contact with the desired object. A further feature of the tool is that the stiffening member is removable. Thus, where the tool is being used to retrieve an object which requires that the tool have a very high degree of flexibility, the stiffening member is removed and then the entire length of the tool can be bent in virtually any type of configuration.
