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 cons ...

Garden Tools
A garden is a planned space, usually outdoors, set aside for the cultivation, display, and enjoyment of plants and other forms of nature. The single feature identifying even the wildest wild garden is ''control''. The garden can incorporate both natural and artificial materials. Gardens often have design features including statuary, follies, pergolas, trellises, stumperies, dry creek beds, and water features such as fountains, ponds (with or without fish), waterfalls or creeks. Some gardens are for ornamental purposes only, while others also produce food crops, sometimes in separate areas, or sometimes intermixed with the ornamental plants. Food-producing gardens are distinguished from farms by their smaller scale, more labor-intensive methods, and their purpose (enjoyment of a pastime or self-sustenance rather than producing for sale, as in a market garden). Flower gardens combine plants of different heights, colors, textures, and fragrances to create interest and delight the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Garden Fork
A garden fork, spading fork, or digging fork (in the past also an ''asparagus fork'', the same name as a very different utensil) 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. Uses 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. Types Reflecting their differing uses, garden forks have shorter, flatter, thicker, and more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human Factors And Ergonomics
Humans (''Homo sapiens'') or modern humans are the most common and widespread species of primate, and the last surviving species of the genus ''Homo''. They are great apes characterized by their hairlessness, bipedalism, and high intelligence. Humans have large brains, enabling more advanced cognitive skills that facilitate successful adaptation to varied environments, development of sophisticated tools, and formation of complex social structures and civilizations. Humans are highly social, with individual humans tending to belong to a multi-layered network of distinct social groups — from families and peer groups to corporations and political states. As such, social interactions between humans have established a wide variety of values, social norms, languages, and traditions (collectively termed institutions), each of which bolsters human society. Humans are also highly curious: the desire to understand and influence phenomena has motivated humanity's de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alloy
An alloy is a mixture of chemical elements of which in most cases at least one is a metal, metallic element, although it is also sometimes used for mixtures of elements; herein only metallic alloys are described. Metallic alloys often have properties that differ from those of the pure elements from which they are made. The vast majority of metals used for commercial purposes are alloyed to improve their properties or behavior, such as increased strength, hardness or corrosion resistance. Metals may also be alloyed to reduce their overall cost, for instance alloys of gold and Copper(II) sulfate, copper. A typical example of an alloy is SAE 304 stainless steel, 304 grade stainless steel which is commonly used for kitchen utensils, pans, knives and forks. Sometime also known as 18/8, it as an alloy consisting broadly of 74% iron, 18% chromium and 8% nickel. The chromium and nickel alloying elements add strength and hardness to the majority iron element, but their main function is ...

Lopper
Loppers are a type of scissors used for pruning twigs and small branches, like pruning shears with longer handles. They are a larger type of manual garden cutting tool, but not as long as pole pruners (averruncators in British English). Loppers are usually operated with two hands, and have handles typically between and long to give good leverage. Some have telescopic handles which can be extended to a length of , in order to increase leverage and to reach high branches on a tree. Loppers are mainly used for the pruning of tree branches with diameters less than . Some of the newer lopper designs have a gear system, a compound lever system, or a ratchet drive, which increases the force applied to the blades. Etymology The word ''wikt:lopper, lopper'' can be used in the singular or the plural, with precisely the same meaning. The plural form, most common in speech but less so in print, is a plurale tantum, and seems to be on the model of a ''pair of scissors''. The name of the to ...

Grass Shears
Grass shears differ from pruning shears in being long-handled and having the handles at right-angles to the blades. They can be used to cut grass from a standing position. Two kinds are available: with the blades horizontal and with the blades vertical. Horizontal blades are used to remove grass which has not been cut by the lawn mower A lawn mower (also known as a grass cutter or simply mower, also often spelled lawnmower) is a device utilizing one or more revolving blades (or a reel) to cut a lawn, grass surface to an even height. The height of the cut grass may be fixed by ..., while vertical blades are used for trimming the edges of a lawn. Background In 1939, a version of the vertical grass shears was invented having a long handle with a lever at the top, and wheels at the bottom with the shears. This enabled the user to trim the edge of the grass near the sidewalk and driveway. Powered trimmers have for all practical purposes replaced this type of grass shears. Referen ...

Anvil Pruners
Pruning shears, also called hand pruners (in American English) or secateurs (in British English), are a type of scissors used for plants. They are strong enough to prune hard branches of trees and shrubs, sometimes up to two centimetres thick. They are used in gardening, arboriculture, plant nursery works, farming, flower arranging, and nature conservation, where fine-scale habitat management is required. They are typically manually powered, although electric versions are available. Loppers are a larger, two-handed, long-handled version for branches thicker than pruning shears can cut. History Cutting plants as part of gardening dates to antiquity in both European and East Asian topiary, with specialized scissors used for Chinese penjing and its offshoots – Japanese bonsai and Vietnamese Hòn Non-Bộ – for over a thousand years. In modern Europe, scissors only used for gardening work have existed since the early 1800s, when the French aristocrat Antoine-François Bertra ...

Steel
Steel is an alloy of iron and carbon that demonstrates improved mechanical properties compared to the pure form of iron. Due to steel's high Young's modulus, elastic modulus, Yield (engineering), yield strength, Fracture, fracture strength and low raw material cost, steel is one of the most commonly manufactured materials in the world. Steel is used in structures (as concrete Rebar, reinforcing rods), in Bridge, bridges, infrastructure, Tool, tools, Ship, ships, Train, trains, Car, cars, Bicycle, bicycles, Machine, machines, Home appliance, electrical appliances, furniture, and Weapon, weapons. Iron is always the main element in steel, but other elements are used to produce various grades of steel demonstrating altered material, mechanical, and microstructural properties. Stainless steels, for example, typically contain 18% chromium and exhibit improved corrosion and Redox, oxidation resistance versus its carbon steel counterpart. Under atmospheric pressures, steels generally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron
Iron is a chemical element; it has symbol Fe () and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, forming much of Earth's outer and inner core. It is the fourth most abundant element in the Earth's crust, being mainly deposited by meteorites in its metallic state. Extracting usable metal from iron ores requires kilns or furnaces capable of reaching , about 500 °C (900 °F) higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BC and the use of iron tools and weapons began to displace copper alloys – in some regions, only around 1200 BC. That event is considered the transition from the Bronze Age to the Iron Age. In the modern world, iron alloys, such as steel, stainless steel, cast iron and special steels, are by far the most common industrial metals, due to their mechan ...

Bronze
Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (including aluminium, manganese, nickel, or zinc) and sometimes non-metals (such as phosphorus) or metalloids (such as arsenic or silicon). These additions produce a range of alloys some of which are harder than copper alone or have other useful properties, such as strength, ductility, or machinability. The archaeological period during which bronze was the hardest metal in widespread use is known as the Bronze Age. The beginning of the Bronze Age in western Eurasia is conventionally dated to the mid-4th millennium BCE (~3500 BCE), and to the early 2nd millennium BCE in China; elsewhere it gradually spread across regions. The Bronze Age was followed by the Iron Age, which started about 1300 BCE and reaching most of Eurasia by about 500 BCE, although bronze continued to be much more widely used than it is in modern times.

Copper
Copper is a chemical element; it has symbol Cu (from Latin ) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable, unalloyed metallic form. This means that copper is a native metal. This led to very early human use in several regions, from . Thousands of years later, it was the first metal to be smelted from sulfide ores, ; the first metal to be cast into a shape in a mold, ; and the first metal to be purposely alloyed with another metal, tin, to create bronze, ...
