Spading Fork
A garden fork, spading fork, or digging fork is a gardening implement, with a handle and a square-shouldered head featuring several (usually four) short, sturdy tines. It is used for loosening, lifting and turning over soil in gardening and farming, and not to be confused with the pitchfork, a similar tined tool used for moving (or throwing) loose materials such as hay, straw, silage, and manure. A garden fork is used similarly to a spade in loosening and turning over soil. Its tines allow it to be pushed more easily into the ground, and it can rake out stones and weeds and break up clods, it is not so easily stopped by stones, and it does not cut through weed roots or root-crops. Garden forks were originally made of wood, but the majority are now made of forged carbon steel or stainless steel. Reflecting their differing uses, garden forks have shorter, flatter, thicker, and more closely spaced tines than pitchforks. They have comparatively a fairly short, stout, usually wood ...

Potato
The potato is a starchy food, a tuber of the plant ''Solanum tuberosum'' and is a root vegetable native to the Americas. The plant is a perennial in the nightshade family Solanaceae. Wild potato species can be found from the southern United States to southern Chile. The potato was originally believed to have been domesticated by Native Americans independently in multiple locations,University of Wisconsin-Madison, ''Finding rewrites the evolutionary history of the origin of potatoes'' (2005/ref> but later genetic studies traced a single origin, in the area of present-day southern Peru and extreme northwestern Bolivia. Potatoes were domesticated there approximately 7,000–10,000 years ago, from a species in the '' Solanum brevicaule'' complex. Lay summary: In the Andes region of South America, where the species is indigenous, some close relatives of the potato are cultivated. Potatoes were introduced to Europe from the Americas by the Spanish in the second half of t ...

Hardpan
In soil science, agriculture and gardening, hardpan or soil pan is a dense layer of soil, usually found below the uppermost topsoil layer. There are different types of hardpan, all sharing the general characteristic of being a distinct soil layer that is largely impervious to water. Some hardpans are formed by deposits in the soil that fuse and bind the soil particles. These deposits can range from dissolved silica to matrices formed from iron oxides and calcium carbonate. Others are man-made, such as hardpan formed by compaction from repeated plowing, particularly with moldboard plows, or by heavy traffic or pollution. Formations Soil structure strongly affects its tendency to form a hard pan. One such common soil condition related to hardpan is soil pH. Acidic soils are most often affected due to the propensity of certain mineral salts, most notably iron and calcium, to form hard complexes with soil particles under acidic conditions. Another major determinant is the soil par ...

Broadfork
The broadfork, also called a U-fork or grelinette, is a garden tool used to manually break up densely packed soil, including hardpan, to improve aeration and drainage. Broadforks are used as part of a no-till or reduced-till seedbed preparation process because they preserve the soil structure and avoid the resurfacing of weed seeds. It consists of five or so metal tines, approximately eight inches long, spaced a few inches apart on a horizontal bar, with two handles extending upwards to chest or shoulder level that form a large U-shape. The operator steps up on the crossbar, using full bodyweight to drive the tines into the ground, then steps backward while pulling backwards on the handles, causing the tines to lever upwards through the soil. This action leaves the soil layers intact, rather than inverting or mixing them, preserving the topsoil structure. A broadfork can be used in a garden, or practically for one to two acres (4,000 to 8,000 m²). For larger areas, a tra ...

Pitchfork
A pitchfork (also a hay fork) is an agricultural tool with a long handle and two to five tines used to lift and pitch or throw loose material, such as hay, straw, manure, or leaves. The term is also applied colloquially, but inaccurately, to the garden fork. While similar in appearance, the garden fork is shorter and stockier than the pitchfork, with three or four thicker tines intended for turning or loosening the soil of gardens. Alternative terms In some parts of England, a pitchfork is known as a ''prong''. In parts of Ireland, the term ''sprong'' is used to refer specifically to a four-pronged pitchfork. Description The typical pitchfork consists of a wooden shaft bearing two to five slightly curved metal tines fixed to one end of a handle. These are typically made of steel, wrought iron, or some other alloy, though historically wood or bamboo were used. Unlike a garden fork, a pitchfork lacks a grab at the end of its handle. Pitchforks with few tines set far apart ...

Spade
A spade is a tool primarily for digging consisting of a long handle and blade, typically with the blade narrower and flatter than the common shovel. Early spades were made of riven wood or of animal bones (often shoulder blades). After the art of metalworking was developed, spades were made with sharper tips of metal. Before the introduction of metal spades manual labor was less efficient at moving earth, with picks being required to break up the soil in addition to a spade for moving the dirt. With a metal tip, a spade can both break and move the earth in most situations, increasing efficiency. A classic spade, with a narrow body and flat (or near flat) tip is suited for digging post holes, and is not to be confused with a "roundpoint" shovel, which has a wider body and tapered tip. Etymology English ''spade'' is from Old English ' (f.) or ' (m.). The same word is found in Old Frisian ' and Old Saxon '. High German ' only appears in Early Modern German, probably loaned fr ...

Garden Tool
A garden tool is any one of many tools made for gardening and landscaping, which overlap with the range of tools made for agriculture and horticulture. Garden tools can be divided into hand tools and power tools. Hand tools Today's garden tools originated with the earliest agricultural implements used by humans. Examples include the hatchet, axe, sickle, scythe, pitchfork, spade, shovel, trowel, hoe, fork, and rake. In some places, the machete is common. The earliest tools were made variously of wood, flint, metal, tin, and bone. The development of metalworking, first in copper and later in bronze, iron, and steel, produced today's durable tools, including such efficient cutting tools as pruning shears (secateurs – for example anvil pruners), grass shears, and loppers. Increasing use of modern alloys allows many tools to be made both stronger and lighter, making them more durable and easier to use. Ergonomics Some modern tool designs reflect ergonomic considerations, ...

The Engineer (UK Magazine)
''The Engineer'' is a London-based monthly magazine and website covering the latest developments and business news in engineering and technology in the UK and internationally. History and description ''The Engineer'' was founded in January 1856. It was established by Edward Charles Healey, an entrepreneur and engineering enthusiast with financial interests in the railways whose friends included Robert Stephenson and Isambard Kingdom Brunel. The journal was created as a technical magazine for engineers. ''The Engineer'' began covering engineering including inventions and patents during a high point of British economic manufacturing power. In the 19th century it also published stock prices of raw materials. Together with the contemporary ''Engineering'' journal the work is considered a valuable historical resource for the study of British economic history. On 10 July 2012 the magazine announced its final print edition, the editor Jon Excell citing "increasing distribution and ...

Lever
A lever is a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge, or '' fulcrum''. A lever is a rigid body capable of rotating on a point on itself. On the basis of the locations of fulcrum, load and effort, the lever is divided into three types. Also, leverage is mechanical advantage gained in a system. It is one of the six simple machines identified by Renaissance scientists. A lever amplifies an input force to provide a greater output force, which is said to provide leverage. The ratio of the output force to the input force is the mechanical advantage of the lever. As such, the lever is a mechanical advantage device, trading off force against movement. Etymology The word "lever" entered English around 1300 from Old French, in which the word was ''levier''. This sprang from the stem of the verb ''lever'', meaning "to raise". The verb, in turn, goes back to the Latin ''levare'', itself from the adjective ''levis'', meaning "light" (as in "not heavy") ...

Stainless Steel
Stainless steel is an alloy of iron that is resistant to rusting and corrosion. It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Stainless steel's resistance to corrosion results from the chromium, which forms a passive film that can protect the material and self-heal in the presence of oxygen. The alloy's properties, such as luster and resistance to corrosion, are useful in many applications. Stainless steel can be rolled into sheets, plates, bars, wire, and tubing. These can be used in cookware, cutlery, surgical instruments, major appliances, vehicles, construction material in large buildings, industrial equipment (e.g., in paper mills, chemical plants, water treatment), and storage tanks and tankers for chemicals and food products. The biological cleanability of stainless steel is superior to both aluminium and copper, having a biological cleanability comparable to glass ...

Tine (structural)
Tines (; also spelled tynes), prongs or teeth are parallel or branching spikes forming parts of a tool or natural object. They are used to spear, hook, move or otherwise act on other objects. They may be made of metal, wood, bone or other hard, strong materials. The number of tines on tools varies widely – a pitchfork may have just two, a garden fork may have four, and a rake or harrow many. Tines may be blunt, such as those on a fork used as an eating utensil; or sharp, as on a pitchfork; or even barbed, as on a trident. The terms ''tine'' and ''prong'' are mostly interchangeable. A tooth of a comb is a tine. The term is also used on musical instruments such as the Jew's harp, tuning fork, guitaret, electric piano, music box or mbira which contain long protruding metal spikes ("tines") which are plucked to produce notes. Tines and prongs occur in nature—for example, forming the branched bony antlers of deer or the forked horns of pronghorn antelopes. The term ''tine' ...

Carbon Steel
Carbon steel is a steel with carbon content from about 0.05 up to 2.1 percent by weight. The definition of carbon steel from the American Iron and Steel Institute (AISI) states: * no minimum content is specified or required for chromium, cobalt, molybdenum, nickel, niobium, titanium, tungsten, vanadium, zirconium, or any other element to be added to obtain a desired alloying effect; * the specified minimum for copper does not exceed 0.40%; * or the maximum content specified for any of the following elements does not exceed the percentages noted: manganese 1.65%; silicon 0.60%; copper 0.60%. The term ''carbon steel'' may also be used in reference to steel which is not stainless steel; in this use carbon steel may include alloy steels. High carbon steel has many different uses such as milling machines, cutting tools (such as chisels) and high strength wires. These applications require a much finer microstructure, which improves the toughness. Carbon steel is a popular m ...
