Saws are tools used to section softer materials using a harder material with an abrasive edge. They come in various sizes and shapes, including hand saws, chainsaws, band saws, and miter saws. There are many other types of saws available for specific applications.
Saws are one of the most common tools in use today. Dating back to a time beyond recorded history, saws are commonly used in any task that involves sectioning softer materials using a shaped harder material with an abrasive edge. They saw some in a variety of sizes and shapes today and can be fed with all sorts of different mediums. There are hand saws and saws powered by electricity, natural gas, steam and even water.
The most basic of all saws is the hand saw. Simple in design, this saw offers a serrated edge blade and handle that allows the operator to use hand action to move the blade back and forth. The smaller handsaws are ideal for cutting thin logs on young trees or for engaging in some sort of woodworking using thinner sections of wood. Some handsaws feature blades that cut through thin sections of metal without dulling.
Perhaps the most commonly recognized hand saw is the crosscut saw. Saws of this type are usually about two feet long and have a set of teeth on the blade portion. People who work with wood planks have traditionally used a hand saw for crosscutting, although it is more common for many builders to use a power saw for large jobs.
Chainsaws are also used a lot today. While still hand held, the chainsaw features a sharp chain mechanism that rotates along a guide to create a cutting motion. This means that the operator does not have to use back and forth motions to cut through a substance. The chainsaw is normally petrol or electric powered, making it easy to use for felling trees and similar tasks.
The band saw is another example of a saw powered by electricity, steam or water. A bandsaw sports a circular blade that spins similar to a wheel. Often, the band saw is fixed in a frame, allowing wood and other materials to be moved against the rotating saw to make the cut. However, portable models of the band saw are also available.
For detail work in creating furniture or crown molding, a miter saw is often used. Miter saws are available in manual versions and electric models. The design of the saw allows for specific cuts to be made allowing for a flush match on various sections going into the building project. A miter saw can be used to create anything from a picture frame to crown molding and baseboards that fit together perfectly.
There are many other types of saws currently in use today. Many of these are designed for very specific applications, while others are intended for more general use. A wide variety of saws are usually available from hardware stores, building suppliers, and some large discount chain stores.
