Westward Hacksaw 21HT83 Hacksaws are versatile tools that can adjust to accommodate blades of different lengths. They are used to make straight, accurate cuts on pipe, tubing, and thin materials that won't bend, snap, or catch the blade. The U-frame of the hacksaw holds the blade under tension, allowing it to cut through metal, plastic, and sometimes wood (depending on the blade). To use a hacksaw, hold the handle at the frame's heel with one hand to move the saw and guide the cut with the other hand at the head of the frame.
