Hand saws have evolved to fill many niches and cutting styles. Some saws are general-purpose tools, such as the traditional hand saw, while others, such as the cutting bow, were designed for specific applications.
The cutting bow is a hand saw type cross-sectional, most common for garden work or outdoors. It uses a relatively long blade with numerous cross teeth designed to remove material by pushing and pulling.
The bow saw is used for pruning trees and cutting logs, but can also be used for other rough cuts.
With a thin, narrow blade, the saw is ideal for cutting jobs, moving debris, and any other cut that requires little to medium precision.
The cutting bows They can be used to cut a wide variety of materials, and can be found in the tool kits of carpenters, plumbers, and even toy or furniture makers.
However, its versatility as a tool does not guarantee the same effectiveness in different scenarios, so it is essential to know the type of saw, length and types of materials that you can cut, before choosing the right one. cutting bow ideal.

Specifically designed for cutting rough wood, a crosscut saw blade has a blade with large bevel teeth. Traditional 2-man crosscut saws, also known as chop saws, have a handle on each end and must be used by two people to crosscut through wood.
The 1-man crosscut saw, or bow saw, is ideal for cutting rough wood such as trees, branches and logs, and is an excellent saw to take camping or store on the job site.
The coping saw, is much more like a saber or jigsaw, and has a long, thin blade for making intricate cuts. The scroll saw blade has a longer, larger arc that allows it to cut further from the outer edges, but the blade cannot be rotated, resulting in more tedious and difficult cutting positions when doing intricate scroll work.
hacksaw blade It is perfect for cutting pipes and tubes, the cutting bow Hacksaw is one of the most common types of hacksaw. They are lightweight and versatile, capable of cutting wood, metal, plastic and other materials using material-specific cutting blades with a tooth count between 18 and 32 per inch.
When looking for a cutting bow, you must take into account the tension adjuster or tensioner. Sheet tension can change due to age, temperature, and humidity. The tensioner is easy to use and will eradicate these problems. Modern bows come with an automatic tension adjuster.
The saw blades They are also differentiated according to the number of teeth per inch. Here we explain in detail:
4 to 6 teeth per inch: Used on miterbows, the Peg tooth blade is designed for cutting dry, hard wood. While the Raker or American toothing is designed to cut wet wood, since it has groups of 4 triangular teeth followed by 1 rake tooth.
12 teeth per inch: They are useful blades for medium diameter pipes, plastic and metal elements, as well as wood.
14 teeth per inch: They work with soft metals like aluminum. They are also used to cut plastic or wiring, being very useful in common household tasks.
18 teeth per inch: optimal for iron pipes and even steel objects. Without a doubt, it will be able to cut elements of high hardness, even if they present corrosion, without seriously affecting the cutting blade.
24 teeth per inch: designed to cut iron, tubes of medium thickness, and are very useful in construction to cut screws, nuts, etc.
32 teeth per inch: Used to make fine cuts in thin metal pipes. A blade with 32 teeth per inch provides more accurate cuts.
Cutting bow: uses according to the work to be done
Is the wood you want to cut green or dead?
If the wood is green, then we should use a green wood blade. American toothed green wood bladesThey have separate teeth that are designed to cut their way through the wood. The pattern is regular, but is usually made up of teeth that are angled forwards and backwards, as well as some that are perpendicular.
If the wood is dead, then we should use a deadwood blade. Deadwood Blades or Serrated PegThey have regularly spaced teeth that are generally at 90º to the blade, unlike woodworking saws that tilt forwards or backwards, depending on the country of origin of the saw you purchased.
Is the wood you want to cut thicker than your wrist?
If the wood is thicker than your wrist then you should use a cutting bow. If the wood is thinner than your wrist, a folding saw might suffice.
The thickness of the wood we want to cut will determine the length of the bow we use. Folding saws are by their very nature short, so they’re only really good for small jobs. Bows, however, come in many different shapes and sizes.
Difference in the length of the cutting arcs
The cutting bows they usually start at 17” long but can extend to around 30” or more, and are designed in such a way that they can be used for more intensive work such as felling a tree and cutting logs.
The shorter saws are often triangular. This helps to get into difficult places, for example, when you want to cut a stick or branch, but because the other branches of the bush are too close together, it is difficult to reach a particular one.
The cutting bows larger ones look, well, like bows. They have a strong metal bow, a tensioner to make the blade as tight as possible, and a handle.
When selecting a chopping bow you should also check that there is a guard that fits all the teeth of the blade. These are cutting tools potentially dangerous, so they should be kept as secure as possible.
A well maintained miter saw can cut a 25cm diameter log in a couple of minutes..
Some cutting bows sell additional replacement blades or include warranty. But you can also buy extra blades online or at a store that has the types of tools for sale. However, 1 or 2 extra blades are not a bad idea. There’s nothing worse than starting a project and stopping halfway through due to a broken blade.
The cutting bows They are lightweight hand tools, easy to transport, and you can be sure that when you use them they work efficiently. That said, all that remains is to select the correct length, the best handle and the ideal blade for the next project to be carried out.
