Those who are accustomed to independently solve construction tasks around the house and household, as a rule, have all the necessary tools in the back rooms. One of them is a hand saw, especially a circular (disk) saw, which is conveniently mounted on a table or workbench. It is noteworthy, but the first prototype of the current saw was invented back in the 20s of the last century, and today this metalwork tool has undergone many changes.
Design features
The circular saw is an electric tool that is operated manually. It can be used for longitudinal and transverse cutting of wood, plastic, chipboard and even soft non-ferrous metals. A hand saw is distinguished by operational work, accuracy, it is advisable to use it when installing a roof, making furniture, laying floors. Thanks to special discs, you can also cut out metal profiles that are needed for furniture design.
As for the design, modern metalwork tools have not changed much compared to previous models. Of course, hand saws have become ergonomic, powerful, compact, and saw blades for them today can be found in a variety of ways, so work can be done with almost anymaterials.
Basic elements
Each hand saw consists of:
- electric motor;
- gear cases;
- protective cover;
- platform and guide.
The case is most often made of high temperature resistant plastic or metal. Ventilation and cooling systems play an important role, as many works are carried out in dusty conditions. The versatility of modern saws is that they can be connected to industrial vacuum cleaners or dust removal systems with special adapters.
The main thing is functionality
How to choose a hand saw to make it as convenient and easy to use as possible? Experts suggest paying attention to the additional systems that many models are equipped with. So, MAKITA 5017 RKB is a bench tool that has a plastic container in the casing of the saw blade, where sawdust is collected, and is equipped with an effective dust extraction system. The model is supplemented with a powerful engine and is capable of performing a vertical cut to a depth of 66 mm. Ease of use, according to users, is provided by a solid base plate and an ergonomic handle.
Worx WT431KE hand saw is another easy-to-use model that attracts attention with a revolving handle that can change the angle of inclination up to 60 degrees. This is very functional, since the operator can work in the way that suits him, that is, based on his own anatomical features.
Batteries - for functionality
Batterycircular saws are considered a new solution. These tools are mains powered, but are additionally equipped with batteries, which significantly expands the scope of their application. Among the models popular with users are the BOSCH GKS 36 V-LI Professional circular saw, which is powered by a lithium-ion battery.
When choosing a model, you should pay attention to the design features of its platform: a saw with a stamped platform is suitable for domestic use, and for professional use it is better to choose a tool in which the platform is cast aluminum. It is also important whether the saw blade can be changed.
Handmade models the old fashioned way
Electric saws are good, convenient, functional, but they can only be used where it is possible to connect to a power outlet. A hand saw for wood is more versatile, which can be taken both into the forest and into nature. An important role is played by the teeth, which have two tasks - cutting the fibers and raking out the resulting sawdust. Therefore, when choosing a hand saw, pay attention to the distance between the teeth - it should be enough to remove sawdust.

In field conditions, compact but functional equipment plays an important role. Hand sawtourist will definitely come in handy, for example, if you need to collect materials for a fire. Such models are lightweight, and the main component in them is a fishing line or chain. Quality tools are suitable for sawing trees of any diameter, and due to the convenient design, the saw can be brought directly under the trunk. The chain in such saws is created on the basis of high-strength carbon steel, and the anti-corrosion coating allows the tool to be used in any climatic conditions.

Sharpening features
Any saw starts to wear out sooner or later. Rather, its canvas wears out, in which the teeth become dull. And they are the main cutting element of any manual model.

You can restore the cutting ability of the teeth by sharpening them with files or needle files, and you need to monitor not only their sharpness, but also parameters such as angles, steps and height. And for this you should follow a number of rules:
- The saw blade must be firmly fixed in the special tool.
- For sharpening, you need a fine-cut file or needle file.
- When sharpening with your right hand, you need to hold the handle of the file, with your left hand, hold its end, directing the file itself to the teeth.
- Press the teeth smoothly and evenly.
- Metal from the edges of the teeth must be ground to the same thickness.
- Tooth edge burrs must be removed as they will dull over time and reduce tool performance.
- The direction of movement of the file depends on whether the tool cuts longitudinally or transversely.
After the saws are sharpened, you need to evaluate them for sharpness. Whatever model you choose, it is important that they are universal, that is, suitable for different building materials.
