Clamps help keep your workpiece steady for cutting, joinery, and assembly. You can also use clamps to create custom fixturing for your projects. For example, say you need to ensure a square cut with a circular saw. As long as you know the width of the foot on your saw, with some clamps, a speed square, and a 2×4 as straight edge, you can make a quick guide for precise cuts or if you clamp it longways it can even be used for rip cuts.
