When hand hacksawing in an area where the possibility of blade breakage is high, it would be better to use:

Explanation:
When blade breakage is likely, choose a flexible-back hacksaw blade because the backing can bend a little as you cut. That flexibility acts like a spring, absorbing shocks from binding or hitting hard spots and spreading the load along more of the blade. This reduces the peak stress that causes a break. A rigid blade has almost no give, so a sudden snag or misalignment can snap it. A blade that’s long or thick isn’t inherently safer for breakage—the stiffness and leverage can actually make breakage more likely under side load. So the flexible-back blade best handles the irregularities and binding you’d encounter in tough cuts.
