In my understanding… Bending plywood is solid plywood where the grain is all oriented in the same direction. Often it is laid with a cloth or other substrate between the layers for stability. So with all the grain in the same direction it is quite flexible. Kerfed board can be bought or made. It is has kerfs cut partially in the back, up to a veneer or to the last layer of ply wood. this allows if to be bent as well. Kerfed board is usually applied to a backing sub straight, like the sub frame of a desk, or an arched cased passage opening. Bending ply is usually used for laminations, where the curve is the structure. I prefer bending ply wood. here is a you tube explanation of kerf board.
