Saws are an indispensable tool that has been around since ancient times. Today, saws are mainly categorised into two types: electric and manual hand saws. Electric saws are ideal for many projects as they do the hard work for you and can make more precise cuts than hand saws. Electric saws can be further divided into corded and cordless varieties. On the other hand, hand saws are powered by the force of the user and are a good option for general-purpose cutting.

Manual hand saws
A non-electric saw is called a manual hand saw. Manual hand saws are powered by human force rather than electricity, batteries, or gas. They are versatile and easy to use, making them an essential part of any toolbox.
There are many types of manual hand saws, each with its own unique features and applications. For instance, a backsaw is used for specific applications where a standard hand saw may not be as effective. It cuts on the pull stroke, providing greater control and eliminating the possibility of the saw kinking in the kerf.
Another type of manual hand saw is the keyhole saw, which is used for cutting small, awkward shapes and holes, especially in drywall or other soft materials. It is ideal for electrical work or projects requiring precise holes in walls.
The drywall saw is also a manual hand saw with a long, tapered blade that comes to a point. It is used for cutting holes in subflooring for plumbing or electrical wiring, and for cutting wallboard, gypsum, and backing board.
The bow saw is a large manual hand saw with a long blade stretched between the ends of a bow-shaped frame. It is often used for pruning trees, cutting firewood, or making rough cuts in lumber for construction projects.
Proper maintenance is important for manual hand saws. They should be stored in a safe, dry place or a toolbox to avoid rust and kept away from other metal tools that might dull the blade. Lubrication with hardware lubricants is also recommended to prevent rust.

Electric saws
One common type of electric saw is the circular saw, which is highly versatile and can make precise cuts in a variety of materials. Circular saws use a disc-shaped blade with sharp teeth that rotates around a shaft. They are small, portable, and can be used to make straight cuts, crosscuts, and angle cuts with bevel adjustments.
Another type of electric saw is the jigsaw, which is ideal for making intricate cuts and curved lines in materials like wood and plaster. Jigsaws have a reciprocating spindle, allowing for more delicate and detailed work than a circular saw. For heavy-duty tasks that require more power, a corded electric saw is recommended, while cordless saws offer greater portability and convenience for confined areas.
Electric chainsaws are also available, which are typically used for woodworking, tree felling, and cutting tree logs. They offer increased mobility and precision compared to traditional hand saws. Other specialised electric saws include concrete saws for masonry or asphalt work, chop saws for metal and tough materials, and reciprocating saws for demolition and remodeling projects.
When choosing an electric saw, it is important to consider the material being cut, the need for portability, and the type of cut required. Electric saws can be dangerous to operate, and some may require special training. However, they offer significant advantages in speed, accuracy, and ease of use compared to hand saws.

Gas-powered saws
Non-electric saws are known as hand saws or power saws, the latter of which are powered by gas motors, rechargeable batteries, or both. Gas-powered saws are a type of power saw that offers several advantages over electric saws.
One notable feature of gas-powered chainsaws is their high-powered engines, which deliver more torque and cutting speed. This extra power makes them particularly effective for cutting through dense or thick materials, such as large tree trunks or metal pipes. Gas-powered chainsaws typically have longer bars, which enable deeper cuts and make them suitable for larger-scale tasks.
However, it's important to consider the drawbacks of gas-powered saws. They tend to vibrate more due to their powerful engines, which can make them more challenging to control and cause user fatigue over extended periods. Gas-powered saws also require proper maintenance, including regular refueling and engine servicing, to ensure optimal performance.
Additionally, gas-powered saws can be noisier and produce more emissions compared to their electric counterparts. As a result, they may not be suitable for use in noise-sensitive areas or for users concerned about their environmental impact. Nevertheless, advancements in technology have led to the development of more efficient and environmentally friendly gas-powered saws, such as those with improved ignition systems for smooth operation and reduced emissions.

Chainsaw types
Chainsaws are available in various types, each with distinct features and pricing. The most suitable chainsaw for you will depend on how you intend to use it.
One way to classify chainsaws is based on their power and technical features, which make them more or less suitable for specific applications. Chainsaws can be classified into compact, medium power, and professional chainsaws. Compact chainsaws are easy to use and versatile, making them ideal for light pruning, cutting small firewood, and DIY tasks. Medium power chainsaws are suitable for intensive and frequent pruning, cutting small to medium-diameter boles, and limbing trees. Professional chainsaws are extremely powerful and designed for intensive jobs and prolonged use, such as felling and sectioning large trees. They are indispensable for woodcutters, gardeners, and groundcare professionals. Pruning chainsaws are a type of professional chainsaw that is lighter and more compact, specifically designed for pruning and limbing duties at heights.
Another way to classify chainsaws is based on their power source. The three basic groups are petrol-engine, electric, and battery-powered chainsaws. Petrol-engine chainsaws are ideal for periodic tending of trees in gardens and tree surgery duties in woodland areas. Electric chainsaws are typically used for felling trees, removing tree limbs, and cutting tree logs for firewood. Battery-powered chainsaws are becoming increasingly popular due to their portability, lightweight design, and fast charge time. They are perfect for smaller jobs around the home, such as cutting firewood, felling small branches, and general trimming.
When choosing a chainsaw, it is important to consider your experience level, the frequency of use, and the specific tasks you plan to undertake.
