What Is a Hand Saw?
A hand saw is a manual saw capable of cutting various materials including metal, plastic, wood, and polyvinyl chloride. Its versatility and independence from a power source make it an ideal tool for home use.
There are two main types of hand saws: those with replaceable blades and those with fixed blades. The replaceable blade type offers more flexibility for different applications and longevity, as the blade can be switched out as needed.
Uses of Hand Saws
Hand saws are commonly used for cutting metal, plastic, wood, and other materials, especially in DIY carpentry, and for breaking down bulky waste at home. They are particularly effective for cutting materials with smaller cutting areas, such as pipes and bars. For cutting aluminum, stainless steel, plastic panels, and pipes, a hand saw is often preferred over a wood saw.
They are handy tools to keep at home for various cutting needs.
Principle of Hand Saws
Hand saws typically feature a bow-like body with a thin, narrow blade. The blade is tensioned using a screw at the tip, preventing bending during use and facilitating the cutting of hard materials. Handles are often an extension of the blade, designed for comfortable grip and efficient force application. They may be rubber-coated or wooden, and some models feature a vertical grip, like Western saws, for enhanced force application, especially for cutting harder materials.
The blades are usually made of durable materials like bimetal or cobalt, ensuring longevity and safety, as they are less likely to shatter if broken. Some hand saws are stringless and more suited for cutting smaller parts due to lower blade tension.
