The earliest reference I could find on chainsaws comes from the Canadian Medical Association Journal in an article written by Wolf Seufert, MD, DSc: “Orthopedics became a specialty with the help of a new instrument, the osteotome, invented around 1830 by the German Bernard Heine. This illustration from a contemporary inventory of surgical tools shows clearly that this clever master of prosthetics had in fact invented the chain saw. The links of the chain carried small cutting teeth with the edges set at an angle; the chain was moved around a guiding blade by turning the handle of the sprocket wheel.” History of the Oregon ChainsawLogger/inventor Joseph Buford Cox was an experienced operator of the gas-powered chainsaws and came up with a revolutionary new chainsaw. Atom IndustriesIn 1972, Atom manufactured their own chainsaws and were the world’s first chainsaw company to have a complete range of chainsaws with electronic ignitions and turbo-action, self-cleaning, air cleaner.
Three years later, in 1929, Stihl developed a gas-powered chainsaw version; however, Emil Lerp, founder of Dolmar chainsaw company, had already begun manufacturing gas-powered chainsaws in 1927. Although Stihl and Dolmar both created chainsaws around the same time, Andreas Stihl is credited as the person who invented the mobile and motorized chainsaw.

Whether these saws were used for working on wood is not known. Up until the 16th Century there is no proof, that hand saws were used in forestry work. To some extent the saw was unknown and in certain places the felling of trees using a saw was forbidden.
One of the earliest patents for an “Endless chain saw” comprising a chain of links carrying saw teeth was granted to Frederick L. Magaw of Flatlands, New York in 1883, apparently for the purpose of producing boards by stretching the chain between grooved drums. “Usually, each segment in a chain features small, sharp, cutting teeth. Each tooth takes the form of a folded tab of chromium-plated steel with a sharp angular or curved corner and two beveled cutting edges, one on the top plate and one on the side plate. Left-handed and right-handed teeth are alternated in the chain. Chains are made in varying pitch and gauge; the pitch of a chain is defined as half of the length spanned by any three consecutive rivets, while the gauge is the thickness of the drive link where it fits into the guide bar. The conventional”full complement” chain has one tooth for every two drive links. Lack of chain oil, or using an oil of incorrect viscosity, is a common source of damage to chainsaws, and tends to lead to rapid wear of the bar, or the chain seizing or coming off the bar.
