What is this crazy felling the tree that he didn’t plant it and crime against nature when he dies don’t have wood for his box they’re going to bury the tip of the head on the floor and walk out to the owls I slept on.
A saw (or chainsaw [1]), an electric- portable, gasoline-powered, or battery-powered saw cuts with a set of teeth attached to a rotary chain driven along a guide bar. Used in activities such as tree felling, limbing, bucking, pruning, cutting of forest trails to suppress land fires and harvesting fires. Chainsaws with specially designed rod and chain combinations have been developed as tools for use in chainsaw craft and chainsaw mills. Special chainsaws are used to cut concrete during construction developments. Chainsaws are sometimes used for ice cutting, for example ice sculpture in Finland and swimming in winter.
The origin of chainsaws in surgery is discussed. A "flexible saw", consisting of a finely serrated link chain held between two wooden handles, was pioneered in the late 18th century (circa 1783--1785) by two Scottish physicians John Aitken and James Jeffray, for symphysiotomy and excision of the diseased bone, respectively. [2] It was cited in the second edition of Aitken's Principles of Midwifery or Puerperal Medicine (1785) in the context of Pelviotomy. [3] Jeffray at the time claimed to have independently conceived the idea of a chainsaw, but it was not until 1790 that he could produce it. In 1806, Jeffray published "Cases of Excision of Carious Joints" by H. Park and PF Moreau. James Jeffray, MD's Observations "In this correspondence, Moreau translated the 1803 article. Park and Moreau described the successful excision of diseased joints, particularly the knee and elbow. Symphysiotomy had a lot of complications for most obstetricians, but Jeffray's ideas were adopted, especially after the development of anesthetics.Mechanized versions of the chainsaw were developed, but in the late 19th century, it replaced the gigli twisted wire saw. For most of the century, the chainsaw was a useful surgical tool.
