Cordless saws have become important tools for woodworkers, increasing their productivity and helping save the environment. Starting from basic designs, these tools have evolved with industrial progress and increased focus on protecting nature.
Whether you're a forest worker, a DIY enthusiast, or a tech lover, the story of cordless saws provides valuable insights into the tools that influence our world.

2. The Early History of the Chainsaw
2.1 Origins and Initial Purposes of Chainsaw
Back in the early 1800s, people were already using saws, including large circular and band saws in England, to cut wood to the sizes they needed. But for thicker trunks, axes were still the go-to tool because saws just couldn't handle them.
Did you know?
According to Jennifer Walker-Journey (2024), in the late 18th century, Scottish doctors John Aitken and James Jeffray adapted a flexible chainsaw, originally designed to ease childbirth.
The Aitkens flexible chainsaw, an innovative tool, made it easier and more precise to remove the pelvic bone during childbirth, causing less damage to nearby tissues. It had a fine serrated chain and teardrop-shaped handles for easy maneuvering behind the pubic bone.
The modern chainsaw's history begins with Bernhard Heine, a German orthopedist. In 1830, he invented the first chainsaw, the "osteotome" (from the Greek words for "bone" and "cutter"), primarily used in medical settings and operated manually.
The chainsaw as we know it today began to evolve in the 1920s. Innovators like Wolf in the USA, Westfelt in Sweden, and Stihl in Germany played key roles. Stihl, which was founded in 1926, quickly became a leading name in chainsaw production, reaching a yearly turnover of 1.6 billion Euros by 2004.
The main idea behind creating chainsaws was to make forestry work, which was very labor-intensive, both easier and more profitable by using machines.
By the late 1920s, petrol chainsaws were introduced, initially needing two people to operate them because of their design and weight, aimed at resembling traditional saws. Petrol chainsaws are used to this day in forestry. Here is an example of an image below:
Despite their potential to make forestry work easier, chainsaws weren't quickly adopted because they were heavy, awkward to handle, and used a lot of fuel, especially the models designed for two people. Early versions of these two-man chainsaws weighed more than 60 kilograms.

The first chainsaw made for just one person came out in 1950, but it was still quite heavy. By 1959, these chainsaws had become lighter, weighing around 12 kilograms, signaling a move towards more manageable designs (modern chainsaws usually weigh between 4-5 kilograms, with the bigger ones weighing 7-9 kilograms).

Chainsaws became more popular and helped address the shortage of lumberjacks in the late 1950s, making the profession more attractive to the younger generation.

However, not everyone was in favor of using chainsaws. Some people called for restrictions, debating whether they were better than traditional tools like axes.

For instance, in 1957, there were worries that the efficiency of chainsaws could lower the rates paid for piecework, leading some lumberjacks to occasionally go back to using hand saws for certain jobs.

2.2 Revolutionizing Forestry: Modern Chainsaw Technological Advances
In 1959, Husqvarna launched the Husqvarna 90 chainsaw with innovative mufflers that greatly reduced noise, setting a new standard. Stihl introduced the first anti-vibration handle in 1964, and Husqvarna improved this with the Husqvarna 180, leading to exports to North America.

A breakthrough came in 1973 when Husqvarna introduced the automatic chain brake, significantly improving chainsaw safety and preventing injuries. In 1980, the Husqvarna 40 used lightweight composite materials, making it easier and more comfortable to use for longer periods.

In 2009, Husqvarna's AutoTune feature automatically adjusted fuel flow, optimizing performance and reducing emissions. Then, in 2012, Husqvarna released battery-powered chainsaws, matching petrol chainsaw performance but with no direct emissions and lower noise, making maintenance easier and further reducing vibration.

3. Technological evolution: from corded to cordless
3.1 Cutting the cord: from corded to smart technology chainsaws
The evolution of chainsaw technology from corded chainsaws to advanced cordless chainsaws represents a major leap forward in terms of convenience and efficiency for users.

1990s: The first cordless chainsaw is introduced, giving users the freedom to work without being tied to an electrical outlet. The first models used nickel-cadmium (NiCd) batteries, but were slightly less powerful and did not last as long as corded chainsaws.
Early 21st Century: Chainsaw lithium-ion (Li-ion) batteries began to power cordless tools such as chainsaws. These batteries have higher power, longer life, and are lighter in weight. This greatly improved the usability and performance of cordless chainsaws.
2010s: Husqvarna and Stihl, the leading innovators in chainsaw technology, developed cordless models that were more efficient, lighter and had better battery performance. These models are comparable in power to pneumatic chainsaws, but without the emissions, noise and maintenance that make them attractive to professionals and home users alike.
Mid-2010s to present: Efforts have been made to improve chainsaws by increasing their power and efficiency and adding smart technology. Common features now include brushless motors that utilize power more efficiently, Bluetooth connectivity that can be easily monitored and adjusted from a smartphone, and on-board diagnostics that alert the user to maintenance needs.
3.2 Breakthroughs in Battery Technology and Efficiency
Improvements in battery technology have played a critical role in increasing the efficiency and popularity of cordless chainsaws, both in the professional arena and for home use.

The shift from nickel-cadmium (NiCd) batteries to lithium-ion (Li-ion) batteries was a dramatic one. Li-ion batteries are lighter in weight, charge faster and last longer than NiCd batteries, making them a huge change for users.

Lithium-ion batteries are a better choice than the older NiCad batteries, especially for devices that need to run for long periods of time, such as chainsaws. Lithium-ion batteries are smaller and lighter, so they can last longer on a single charge, making them perfect for tools that require a lot of power.

Unlike NiCd batteries, lithium-ion batteries don't have a "memory effect," which reduces their efficiency if you don't fully deplete them before recharging. You can recharge them whenever it's convenient for you without compromising battery life or performance. In addition, they hold a charge longer when not in use. This makes them more reliable and easier to use for a variety of tools and equipment.

Recent improvements employ better battery use technology, a technology that automatically adjusts fuel flow based on tool use to increase battery efficiency and life.The Pelifish HP219 chainsaw also utilizes this battery technology and offers a 10C discharge high power battery that keeps the chainsaw from stalling and cutting wood like clay.

These innovations not only improve the performance of cordless chainsaws, but also reduce emissions and noise pollution, making them environmentally friendly.

Now, lightweight, battery-powered chainsaws are changing the landscape.

Landscapers can use a cordless chainsaw to prune or clear debris anywhere on a property, without worrying about cord length or needing fuel.

Homeowners also find it easier to take care of their yards without the daunting task of starting and maintaining a gas saw.
Professionals in remote locations, like forest service employees or disaster relief teams, can now easily take powerful tools to places that were difficult to access before.

This improvement in how easy it is to carry chainsaws around not only makes them simpler to move but also results in their use being more efficient, convenient, and better for the environment in both professional and home environments.
