There are a variety of saws out there for all kinds of tasks, and many of them are specialized -- and pretty dangerous to use. If you have to cut a bit of metal, cable or pipe, though, the lowly hacksaw is fast and effective. It won't cost a fortune, either. Hacksaws are easy to grip and have fine-toothed blades that get the job done without giving your upper body a workout you'll regret later. For small wood jobs, a crosscut saw is also a good option. It won't do fine work, but it's up to the task of cutting the occasional two by four without making a big production of it.
