Confirm Blade Damage

What happens here

Place the removed blades individually on a flat, level surface, such as concrete. Observe if the entire blade lies flat or if any part of it is lifted or warped. A bent blade will not sit completely flat. The video clearly shows one blade with a significant bend, confirming it as the source of the vibration. Compare with new blades if available.

Goal: Positively identify bent or damaged blades.
