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.

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.

Others might point to the inventions of Stihl and Lerp in the 1930s, and others still might claim the modern chainsaw wasn’t invented until the first one-man saws arrived after the Second World War. In a way, it is irrelevant which of these steps truly represents the first chainsaw since the modern chainsaw is the descendant of all these inventions.
Whether these saws were used for working on wood is not known. Around 750 B.C. iron replaced bronze as a working material but saws remained out of bronze for many centuries. Up until the 16th Century there is no proof, that hand saws were used in forestry work. Around 1500 Leonardo da Vinci also spent some time on saws. To some extent the saw was unknown and in certain places the felling of trees using a saw was forbidden. Employers then provided the saws, which meant that lumberjacks sank from being self employed artisans to wage workers. Although the saw was already known in antiquity, it was only widely put into use in the forest in central Europe towards the middle of the 18th Century.
