Backsaws are hand saws with a strip of steel or brass running along the back of the blade, making them suitable for cutting wood and creating joints or grooves. They are smaller than a table saw and come in two specialized versions: the tenon saw and the dovetail saw. Backsaws should be used with a clamp or vice and sharpened regularly to prevent safety hazards.
The backsaw is a cutting tool with a strip of steel or brass running along the back of its blade; this area is known as the “back”. The weight of its back and its sharp, serrated teeth make the back saw blade suitable for cutting wood. In fact, back saws are typically used to create joints or grooves in wood. They’re a great choice for the woodworking and woodworking enthusiast because they’re versatile, efficient, and also tend to be smaller than a table saw.
Technically, back saws fall into the hand saw category. Like handsaws, their design consists of a long, serrated piece of metal with a handle at one end. This basic design is what most people think of when they picture a saw. Backsaws, however, are a miniature version of the classic handsaw. Their hardened blades typically measure anywhere from 8 to 14 cm (20.3-35.5 inches) in length with 11-20 serrated teeth per inch.
Backsaws should always be used with a clamp or vice. To cut joints in wood, a carpenter or carpenter will first make sure his project is securely clamped, then grip the backsaw handle with his forefinger running along the top of the blade for added support. The first few cuts should be made smoothly, with the blade moving away from the body. After a groove is established, it becomes easier to move back and forth in the traditional sawing motion.
Due to its size and shape, the backsaw is best suited for cutting joints and tenons. There are actually two specialized versions of the backsaw that have been developed around these purposes. The most common tenon saw makes general purpose cuts and larger joints. The dovetail saw, as the name suggests, is intended for making the small cuts necessary to create a dovetail joint.
Back saws are manually operated, so taking care of this tool means sharpening it regularly. Those small, sharp teeth need to be kept in top condition. Otherwise, backsaw cuts can become rough and uneven, and the teeth may even get stuck in the wood instead of biting into it. Safety hazards can arise any time you let a saw go dull, and this is especially true of hand saws, which can slip or stick and cause injury.
