Loppers
Loppers are a type of scissors used for pruning twigs and small branches, like pruning shears with very long handles. They are the largest type of manual garden cutting tool. They are usually operated with two hands, and with handles typically between and long to give good leverage. Some have telescopic handles which can be extended to a length of two metres, 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 or compound lever system which increases the force applied to the blades, or a ratchet drive. Etymology The word ''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 tool is derived from the verb "to lop", meaning to cut off (especially branc ...

Scissors
Scissors are hand-operated shearing tools. A pair of scissors consists of a pair of metal blades pivoted so that the sharpened edges slide against each other when the handles (bows) opposite to the pivot are closed. Scissors are used for cutting various thin materials, such as paper, cardboard, metal foil, cloth, rope, and wire. A large variety of scissors and shears all exist for specialized purposes. Hair-cutting shears and kitchen shears are functionally equivalent to scissors, but the larger implements tend to be called shears. Hair-cutting shears have specific blade angles ideal for cutting hair. Using the incorrect type of scissors to cut hair will result in increased damage or split ends, or both, by breaking the hair. Kitchen shears, also known as kitchen scissors, are intended for cutting and trimming foods such as meats. Inexpensive, mass-produced modern scissors are often designed ergonomically with composite thermoplastic and rubber handles. Terminology The noun ' ...

Pruning Shears
Pruning shears, also called hand pruners (in American English), or secateurs (in British English), are a type of scissors for use on 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. 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 1819, when the French aristocrat Antoine-François Bertrand de Molleville was listed in "Bon Jardinier", as the inventor of secateurs. During the ...

Pruning
Pruning is a horticultural, arboricultural, and silvicultural practice involving the selective removal of certain parts of a plant, such as branches, buds, or roots. The practice entails the ''targeted'' removal of diseased, damaged, dead, non-productive, structurally unsound, or otherwise unwanted plant material from crop and landscape plants. Some try to remember the categories as "the 4 D's": the last general category being "deranged". In general, the smaller the branch that is cut, the easier it is for a woody plant to compartmentalize the wound and thus limit the potential for pathogen intrusion and decay. It is therefore preferable to make any necessary formative structural pruning cuts to young plants, rather than removing large, poorly placed branches from mature plants. In nature, meteorological conditions such as wind, ice and snow, and salinity can cause plants to self-prune. This natural shedding is called abscission. Specialized pruning practices may be ap ...

Plurale Tantum
A ''plurale tantum'' (Latin for "plural only"; ) is a noun that appears only in the plural form and does not have a singular variant for referring to a single object. In a less strict usage of the term, it can also refer to nouns whose singular form is rarely used. In English, ''pluralia tantum'' are often words that denote objects that occur or function as pairs or sets, such as ''spectacles'', ''trousers'', ''pants'', ''scissors'', ''clothes'', or ''genitals''. Other examples are for collections that, like ''alms'' and ''feces'', cannot conceivably be singular. Other examples include '' suds'', ''jeans'', ''outskirts'', ''odds'', ''riches'', ''surroundings'', ''thanks'', and ''heroics''. In some languages, ''pluralia tantum'' refer to points or periods of time (for example, Latin 'calends, the first day of the month', German 'vacation, holiday') or to events (for example, Finnish 'wedding' and 'face'). In some cases there is no obvious semantic reason for a particular noun t ...

Middle English
Middle English (abbreviated to ME) is a form of the English language that was spoken after the Norman conquest of 1066, until the late 15th century. The English language underwent distinct variations and developments following the Old English period. Scholarly opinion varies, but the ''Oxford English Dictionary'' specifies the period when Middle English was spoken as being from 1150 to 1500. This stage of the development of the English language roughly followed the High to the Late Middle Ages. Middle English saw significant changes to its vocabulary, grammar, pronunciation, and orthography. Writing conventions during the Middle English period varied widely. Examples of writing from this period that have survived show extensive regional variation. The more standardized Old English language became fragmented, localized, and was, for the most part, being improvised. By the end of the period (about 1470) and aided by the invention of the printing press by Johannes Gutenberg in 14 ...

Fulcrum (mechanics)
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"). The ...

Gardening Tools
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, be ...
