Loppers
Loppers are a type of scissors used for pruning twigs and small branches, like secateurs 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 & 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 branches or twigs), which in turn is related to a noun of precisely the same form: a "lop" is a period or session of branch cutting. The noun and verb first appeared in Middle English as ''loppe,'' but have no known antecedents or cognates in other languages.
