Hack Saw, 12" blade
A hacksaw is a metal-framed saw used primarily for cutting plastic and metal pipes and other small household materials. The U-shaped bow frame holds a thin, wide blade between its spigots (clips) and a plastic or wood handle at one end. Some models use an adjustable frame to accommodate 8-, 10-, or 12-inch blades as needed. Depending on the cut desired, metal blades will have 14, 18, 24, or 32 teeth per inch, with the denser teeth best for cutting smaller objects.
