In normal hacksaws, the blades are tightened with the help of a wing nut/screw, which gets loose after some use. The innovator has fit the nut inside the frame of the hacksaw and the bolt inside the handle. The bolt of nut passes through the lower end of the frame to hold the blades. To tighten the blade one only has to rotate the handle as per the requirement.
