Tool
A tool is an object that can extend an individual's ability to modify features of the surrounding environment or help them accomplish a particular task. Although many animals use simple tools, only human beings, whose use of stone tools dates back hundreds of millennia, have been observed using tools to make other tools. Early human tools, made of such materials as stone, bone, and wood, were used for preparation of food, hunting, manufacture of weapons, and working of materials to produce clothing and useful artifacts. The development of metalworking made additional types of tools possible. Harnessing energy sources, such as animal power, wind, or steam, allowed increasingly complex tools to produce an even larger range of items, with the Industrial Revolution marking an inflection point in the use of tools. The introduction of widespread automation in the 19th and 20th centuries allowed tools to operate with minimal human supervision, further increasing the productivity of ...

Screwdriver
A screwdriver is a tool, manual or powered, used for turning screws. A typical simple screwdriver has a handle and a shaft, ending in a tip the user puts into the screw head before turning the handle. This form of the screwdriver has been replaced in many workplaces and homes with a more modern and versatile tool, a power drill, as they are quicker, easier, and can also drill holes. The shaft is usually made of tough steel to resist bending or twisting. The tip may be hardened to resist wear, treated with a dark tip coating for improved visual contrast between tip and screw—or ridged or treated for additional 'grip'. Handles are typically wood, metal, or plastic and usually hexagonal, square, or oval in cross-section to improve grip and prevent the tool from rolling when set down. Some manual screwdrivers have interchangeable tips that fit into a socket on the end of the shaft and are held in mechanically or magnetically. These often have a hollow handle that contains various t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Staple (fastener)
A staple is a type of two-pronged fastener, usually metal, used for joining or binding materials together. Large staples might be used with a hammer or staple gun for masonry, roofing, corrugated boxes and other heavy-duty uses. Smaller staples are used with a stapler to attach pieces of paper together; such staples are a more permanent and durable fastener for paper documents than the paper clip. Etymology The word "staple" originated in the late thirteenth Century, from Old English ''stapol'', meaning "post, pillar". The word's first usage in the paper-fastening sense is attested from 1895. History In ancient times, the staple had several different functions. Large metal staples dating from the 6th century BC have been found in the masonry works of the Persian empire (ancient Iran). For the construction of the Pasargadae and later Ka'ba-ye Zartosht, these staples, which are known as "dovetail" or "swallowtail" staples, were used for tightening stones together. The ho ...

Staple Remover
A staple remover (also known as a destapler) is a device that allows for the quick removal of a staple from a material without causing damage. The best-known form of staple remover, designed for light-gauge staples, consists of two opposing, pivot-mounted pairs of thin, steep wedges and a spring that returns the device to the open position after use. Although a simple metal wedge can be used for the same purpose, and although some staplers (especially small ones about long) feature such a wedge at their hinge end, use of the wedge tends to tear fragile papers. Use Proper use of the opposing wedge staple remover is debated; the two major methods are described below. Original method The user clips the front flat side of the staple, forcing the folded tabs on the reverse side to open and pull through the entry holes. Although this method is quick, it may tear the paper during removal. The inventor of the original staple remover, William G. Pankonin, illustrates this method of r ...
