Original ESB/ROTJ stunt Vader saber going up for auction...

I don’t think these dents were from being hit by a blade, I think these dents were from being dropped on the ground between takes and thrown in storage between movies

To me, the blades are weaker than aluminum.. path of least resistance, the blades would break first before the aluminum

But my way of thinking, I have no proof this is the truth.

Agreed.

I think this is pretty safe to say is true; the fencing "blades" were composite resin and fiberglass things. Basically the same as Vader's mask and chest armor. They're anchored to steel and solid cylinders of aluminium. I believe the MPP shrouds were also alu and/or steel, too. It'd going to take something pretty substantial to get it to bow the way it does and where it's bowed at. Maybe it was a repair when the shroud got dented by something else?
