A good hacksaw blade always helps, and bi-metal blades can improve cutting performance. The main disadvantage to using this tool to cut screws is that it can require a fair amount of physical effort depending on the size of a screw being cut. Smaller hacksaws can cost just a few dollars and are a valuable addition to any DIYer’s toolbox. When cutting screws, nails, or bolts, the slender blade makes it easy to reach into narrow gaps.
On small hacksaws, the sprung steel of the frame provides all of the tension necessary to hold the blade, whereas a lever or tensioning knob is used in larger models. They can vary from 6-inch mini hacksaws up to heavy-duty, 24-inch tools. A hacksaw is a general-purpose metal-cutting saw usually defined by its blade length.
