(fiberglass). Hand shovel blades made of sheet steel usually have a folded seam or hem at the back to make a socket for the handle. This fold also commonly provides extra rigidity to the blade. The handles are usually riveted in place. A T-piece is commonly fitted to the end of the handle to aid grip and control where the shovel is designed for moving soil and heavy materials. These designs can all be easily mass-produced. The term ''shovel'' also applies to larger excavating machines called power shovels, which serve the same purpose—digging, lifting, and moving material.

History

In the Neolithic age and earlier, a large animal's scapula (shoulder blade) was often used as a crude shovel or spade.''Concise Oxford Dictionary of Archaeology'', p. 304
It is via this connection between shoulder blades and digging blades that the words '' spatula'' and '' spade'' both have etymologic connection with scapulas. The later invention of purpose-built shovels was a ground-breaking development. Manual shoveling, often in combination with picking, was the chief means of excavation in construction until mechanization via

part of them. Until the 1950s, manual shoveling employed large numbers of workers. Groups of workers called 'labor gangs' were assigned to whatever digging or bulk materials handling was needed in any given week, and dozens or hundreds of workers with hand shovels would do the kind of rapid excavating or materials handling that today is usually accomplished with powered excavators and loaders operated by a few skilled operators.

of the business was tied mostly to labor productivity. It still often is even today; but in the past it was even more so. In industrial and commercial materials handling, hand shoveling was later replaced not only with loaders and backhoes.

pp. 64–75
Taylor, with his focus on time and motion study, took an interest in differentiating the many motions of manual labor to a far greater degree than others tended to. Managers might not care to analyze it (possibly motivated by the assumption that manual labor is intellectually simple work), and workers might not care to analyze it in any way that encouraged management to take away the

Taylor realized that failing to analyze shoveling practice represented a missed opportunity to discover or synthesize best practices for shoveling, which could achieve highest productivity (value for dollar spent). It was Taylor and colleagues in the 1890s through 1910s that greatly expanded the existing idea of varied shovel designs with different-sized scoops, one for each material, based on the material's density. Under scientific management, it was no longer acceptable to use the same shovel for shoveling brown coal one day and gravel the next. Taylor advocated the higher capital cost of maintaining two shovels as more than paying for itself through the increase in worker productivity that it would lead to, which would mean less money being spent on wages for each unit of shoveling work accomplished.
