PETALING JAYA: While horror movie fans can relate to a madman terrorising victims with a chainsaw, the general public understands that this machine is used for tasks like felling trees or pruning bushes.
While the chainsaw is associated with loggers, it was not first used by the timber industry.
Instead, a precursor to the device that we now know as a chainsaw was conceived in 1780 by Scottish doctors John Aitken and James Jeffray.It was used cut through the pelvis of a mother who was having trouble during childbirth. The chainsaw was designed to tear through the mother's flesh, cartilage and bone if the baby was stuck in the birth canal.
And if that was not painful enough, the now-outdated procedure called a symphysiotomy was done without anaesthesia – both the mother had to be conscious throughout the process.Fortunately, with the advancement of medicine and healthcare, childbirth has become more comfortable, safer and hygienic.In 1918, the world was introduced to the first portable gasoline-powered chainsaw, invented by Canadian James Shand.
