The word "back saw" is spelled phonetically as /bæk/ /sɔː/. The "b" and "a" sounds in "back" are pronounced with a short "a" sound and a hard "k" sound. The "saw" part of the word contains a long "o" sound, with a soft "s" sound following it. The "w" is pronounced as a silent letter. This particular type of saw is designed for making accurate cuts in wood, with a rigid blade that is supported by a stiffening rib. Its spelling reflects the sounds of the words that make it up.
A back saw is a specialized hand saw that features a rigid spine along its back edge, which is designed to provide additional support and stability to the blade. This type of saw is commonly used in woodworking and carpentry tasks that require precise and accurate cutting.
The key characteristic of a back saw is its fine and narrow-toothed blade, typically ranging from 8 to 14 inches in length. The blade's teeth are specifically designed for creating clean and smooth cuts with minimal splintering or tear-out. It is usually made of high-quality steel, often hardened for improved durability and sharper teeth.
The rigid back of the saw aids in maintaining the blade's straightness while cutting, preventing it from bending or flexing. This characteristic makes the back saw well-suited for tasks that demand accuracy, such as joinery work, making precise crosscuts or miters, and creating fine furniture.
The handle of a back saw is usually shaped for a comfortable and secure grip, enabling the woodworker to exert control and pressure as needed. Some back saws feature a reinforced handle, further enhancing their stability and reducing the risk of slipping during use.
Overall, the back saw is a valuable and versatile tool in woodworking, offering exceptional precision and control for tasks that require accurate and clean cuts.
The word "back saw" is derived from the combination of two separate terms - "back" and "saw".
The word "back" in this context refers to the spine or the back of the saw blade. It distinguishes the back saw from other types of saws that have a more flexible blade without any stiffening element.
The term "saw" comes from the Old English word "saw, sagu" or the Old Norse word "sög" meaning "cutting instrument". It traces its roots back to the Proto-Germanic word "sagjanan", which translates to "to cut".
Therefore, the word "back saw" essentially describes a type of saw that has a rigid spine or back that provides support to the blade during sawing operations.
