Hand saw

A hand saw is a handheld tool used for manually cutting materials such as wood, metal, plastic, and more. High-quality hand saws are typically crafted from durable materials, offering excellent durability and resistance to wear. They often utilize heat-treated steel strip products made from carbon tool steel, which has undergone a heat treatment process to enhance its properties.
