A jigsaw is a saw designed for making rip cuts in woodworking. Its teeth are flat and act like a chisel, allowing it to easily cut grain lines and achieve a straight cut. It is made with a metal blade and a blade holder and should be stored in a dry area. Replacement blades are available and can be easily installed.
A circular saw is a specialized type of hand saw designed for making rip cuts. A rip cut is a term used in woodworking to describe a cut made parallel to the grain of the wood. Cutting a tree trunk in half from top to bottom, for example, is considered a long cut.
There are many tools that can be used to make a rip cut, such as a table saw, radial alarm saw, hand ripsaw, and band saw. A jigsaw, however, is the only saw made specifically for this purpose. The cutting edge of each saw tooth is made with a flat leading edge. Unlike many other types of saws, the tooth is not angled forward or backward.
The special design of the jigsaw’s teeth allows it to act like a chisel. Unlike the crosscut saw, which has back-angled teeth with beveled edges, the design of the teeth prevents the saw from following grain lines. Acting similar to a chisel, the jigsaw can easily cut grain lines and achieve a straight cut by kicking up tiny splinters of wood. The American-designed saw is created to cut when pushed through the wood, which is called a push stroke. A Japanese jigsaw, on the other hand, cuts on the pull stroke.
A jigsaw is made with a metal blade and a blade holder. The handle is usually made of wood, although it can also be made of metal. As the instrument is made of metal, it must be stored in an area free from excessive moisture to prevent rusting. Also, it’s best to hang the step saw against a wall to prevent moisture from building up on an area of it.
Occasionally, the jigsaw blade needs to be replaced because it becomes dull from use. Also, the blade may break during use, particularly if too much pressure is applied while cutting. Replacement blades are available at hardware stores and home improvement stores. To replace the blade, the user simply removes the screws holding the old blade in place, insert the new blade and screw it back in.
