HAND TOOLS AND METHOD OF FABRICATION THEREOF
An attachment system and method allows reversely operating a working head with a shaft of different lengths selectively. A first hand tool is reversely connected to an extension shaft to obtain a second, longer-shafted hand tool, both fully operational and sturdy for hand-use, according to applications, work conditions and ergonomics. A range of different lengths hand tools may be contemplated, such as shovels, forks, trowels, transplanters, weed cutters, rakes, hoes, planters, and scoops, for example.
BROADFORK ASSEMBLY
A broadfork assembly includes a longitudinal crossbar including a plurality of transverse slots for cooperatively engaging a plurality of removable fork tines. A handle having a pair of spaced apart aligned tubular members cooperatively engages a pair of sockets mounting to a top surface of the longitudinal crossbar. The handles include a transverse hole in the bottom distal end. Removably affixed to the longitudinal crossbar is a plurality of removable forks. The top blade portion includes a top edge having a lug for cooperative engagement with one of the slots in the longitudinal crossbar. The longitudinal crossbar includes a pair of ends or end caps having a center hole therein for insertion of a rod which extends through the handles and a transverse hole in the top blade portion of the curved blades running parallel to the longitudinal crossbar. The rod includes retainer means on each of its distal ends.
