I could be mistaken, but many years ago I believe I learned that plywood is generally made by spinning a log while slicing a thin veneer off the surface, then stacking multiple of those veneers into plywood. The grain on the surface would be notably different when cutting wood with this method compared to sawing planks
Correct. Plywood gets a lot of strength from the alternating grain directions in each layer and the core plys aren’t always the same species as the veneer/face plys.
