Why were chainsaws invented?

 

A chainsaw is a portable, mechanical saw which cuts with a set of teeth attached to a rotating chain that runs along a guide bar. It is used in activities such as tree felling, limbing, bucking, pruning, cutting firebreaks in wildland fire suppression and harvesting of firewood. Chainsaws with specially designed bar and chain combinations have been developed as tools for use in specific industries and environments.

The origin of the chainsaw is debated. A German doctor, Bernhard Heine, is credited with inventing the first chainsaw in 1830. He was a surgeon who needed a more efficient way to remove bone from tissue. Other sources credit Andreas Stihl, who invented and patented the first electric chainsaw in 1926. Stihl’s saw was heavier and less portable than Heine’s. The first gasoline-powered saw was invented in 1905 by Moses W. Green. Green’s saw was heavier and more difficult to start than the electric saws of today. However, it was more powerful and easier to use than the hand saws that were the only other option at the time. Chainsaws became popular in the United States after World War II. They were initially used by farmers and ranchers to clear land. As the suburban population grew, chainsaws were increasingly used by homeowners to clear trees and brush from their yards. The saws became lighter and more powerful in the 1950s and 1960s. This made them more versatile and easier to use. The development of chainsaw-related safety gear, such as chainsaw chaps and helmets, also made them more user-friendly. Today, chainsaws are used for a variety of tasks, including tree felling, limbing, bucking, pruning, and cutting firebreaks. They are also used in the harvesting of firewood. Chainsaws with specially designed bar and chain combinations have been developed for use in specific industries, such as logging and arboriculture.
