ABSTRACT:
A second handle attachment for a tool having a handle shaft, such as a shovel, is disclosed. The second handle attachment provides a grip portion that a user may grab so that the shovel may be used without the user bending over. In this manner, back injury and strain is reduced. The second handle attachment provides two clamshell brackets which are bolted into a rigid relationship with the tool's handle shaft. The attachment also provides a rotating second handle that may be locked into place at any of several angular relationships with the tool handle shaft. The second handle provides a grip portion that is typically covered by a plastic or rubber grip cover. The second handle attachment may be transferred among any type of shovel, rake, snow shovel, hoe or pitch fork. It may be adjusted up or down the handle shaft, to accommodate taller or shorter users. It may be rotated to accommodate right-handed, left-handed or ambidextrous users. A bushing is provided so that the second handle attachment may be used with a light weight rake having a smaller diameter handle shaft, as well as a shovel having a larger diameter handle shaft.
