Abstract: 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.
