For tough jobs, this heavy duty scissors is what you need. For the overall size of it (medium), this tool is a brute. The jaws close tightly and the sawtooth edges are SHARP. I got this to cut heavy fiberglass cloth and mat, carpet for boat trailer bunks and other hard to cut soft sheet materials. It does that with ease. Though it is heavy and not easy to maneuver in tight spaces , in straight line cuts, this tool is a beauty.See full review
