Before the invention of chainsaws, people had to cut firewood by hand. This was a time-consuming and physically demanding task that required a lot of strength and endurance. The most common way to cut firewood by hand was with an axe. Other tools that were used include saws, hatchets, and spears.
The first known chainsaw was invented in the early 1800s by a German doctor named Bernhard Heine. However, it wasn’t until the early 1900s that chainsaws began to be widely used for cutting wood. Chainsaws quickly became popular because they were much more efficient than traditional methods of cutting firewood by hand.
