Scissors are used for cutting various thin materials, such as paper, cardboard, metal foil, cloth, rope, and wire. 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 hand-operated shearing tools.

Using the incorrect type of scissors to cut hair will result in increased damage or split ends, or both, by breaking the hair. Hair-cutting shears have specific blade angles ideal for cutting hair. Hair-cutting shears and kitchen shears are functionally equivalent to scissors, but the larger implements tend to be called shears.

When closed, the dog and cat figures at the tips come face to face. The style of the 'Egyptianizing' metal inlay designs suggests that they were made to imitate actual Egyptian art. And come from a Roman settlement in Trabzon, Turkey. English as a Second LanguageDescripcin completa.Modern scissors are often designed ergonomically with composite thermoplastic and rubber handles which enable the user to exert either a power grip or a precision grip.These shears are thought to date to the 2nd century A.D.

Was producing scissors by 1760, although it is believed the business began trading even earlier. William Whiteley & Sons (Sheffield) Ltd. The center of the bar was heated, bent to form the spring, then cooled and reheated to make it flexible.The Hangzhou Zhang Xiaoquan Company in Hangzhou, China, has been manufacturing scissors since 1663. They entered common use in not only ancient Rome, but also China, Japan, and Korea, and the idea is still used in almost all modern scissors.During the Middle Ages and Renaissance, spring scissors were made by heating a bar of iron or steel, then flattening and shaping its ends into blades on an anvil. However, pivoted scissors of bronze or iron, in which the blades were pivoted at a point between the tips and the handles, the direct ancestor of modern scissors, were invented by the Romans around 100 AD. These were of the 'spring scissor' type comprising two bronze blades connected at the handles by a thin, flexible strip of curved bronze which served to hold the blades in alignment, to allow them to be squeezed together, and to pull them apart when released.Spring scissors continued to be used in Europe until the 16th century.

He achieved strong sales in London and elsewhere. Hinchliffe lived in Cheney Square (now the site of Sheffield Town Hall), and set up a sign identifying himself as a 'fine scissor manufacturer'. This process was laborious, and apparently Hinchliffe improved upon it in order to increase production. His major challenge was to form the bows first, he made them solid, then drilled a hole, and then filed away metal to make this large enough to admit the user's fingers. The company is still manufacturing scissors today, and is the oldest company in the West to do so.Pivoted scissors were not manufactured in large numbers until 1761, when Robert Hinchliffe of Sheffield produced the first pair of modern-day scissors made of hardened and polished cast steel.

For example, if the applied force (at the handles) is twice as far away from the fulcrum as the cutting location (i.e., the point of contact between the blades), the force at the cutting location is twice that of the applied force at the handles. For cutting thick or heavy material, the mechanical advantage of a lever can be exploited by placing the material to be cut as close to the fulcrum as possible. An ideal example is in high-quality tailor's scissors or shears, which need to be able to perfectly cut (and not simply tear apart) delicate cloths such as chiffon and silk.Children's scissors are usually not particularly sharp, and the tips of the blades are often blunted or 'rounded' for safety.Mechanically, scissors are a first-class double- lever with the pivot acting as the fulcrum. The hand movement (pushing with the thumb, pulling with the fingers) can add to this tension. In high-quality scissors, the blades can be both extremely sharp, and tension sprung вЂ“ to increase the cutting and shearing tension only at the exact point where the blades meet.

Some quadriplegics can use a motorized mouth-operated style of scissor.Left-handed (left) and right-handed (right) scissorsMost scissors are best suited for use with the right hand, but left-handed scissors are designed for use with the left hand. In hair cutting, some claim the ring finger is inserted where some place their index finger, and the little finger rests on the finger tang.For people who do not have the use of their hands, there are specially designed foot-operated scissors. A finger tang can be found on many quality scissors (including inexpensive ones) and especially on scissors for cutting hair (see hair scissors pictured below).

However, most 'ambidextrous' scissors are in fact still right-handed in that the upper blade is on the right, and hence is on the outside when held in the right hand. These have symmetric handles so there is no distinction between the thumb and finger handles, and have very strong pivots so that the blades simply rotate and do not have any lateral give. Furthermore, with right-handed scissors held by the right hand, the shearing edge is visible, but when they are used with the left hand, the cutting edge of the scissors is behind the top blade, and one cannot see what is being cut.Some scissors are marketed as ambidextrous. Conversely, if right-handed scissors are held in the left hand, the natural tendency of the left hand would be to force the cutting blades laterally apart.
