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.

Abstract: A snow shovel head, comprising an impeller rotately connected to an axle in a casing, a discharge chute and a chute handle, the casing comprising a back wall, a circumferential wall with an output to the chute, and a cut out bottom wall extending laterally from the back wall of the casing to the front opposite lateral corners of the bottom wall at the circumferential wall of the casing, and centrally from the back wall of the casing to the open front of the casing up to a tip recessed from said lateral corners; and the back wall extending to the lateral corners of the bottom wall at the circumferential wall; the impeller, when rotating, scooping up snow from the open front of the casing to an inner lateral surface of the circumferential wall of the casing towards the output to the chute for discharge of the snow.
