This is another simple tool… not all lumber is straight. It either comes with a twist or gets one when it is waiting to be installed. When the twist happens, it can be challenging to pull the board back to a lined-up position by hand. The Board-Bender fits over the board’s edge and has a handle to allow sufficient torque to be applied to bring it back to being a useful board instead of being cut and used for other purposes or discarded altogether.
