Lightsabers cannot not cut threw anything. Their are things, even in the movies they fail to cut, from metal staffs, to Vaders shoulder armor, to the peices of Bespin Vader chucks at Luke. Those examples are just off the top of my head and from the movies. Once you get into the EU I'm pretty sure there are even more lightsaber resistant materials. Don't the Mandolorian have anti-lightsaber armor or something. Just double checked Wookiepedia which list 7 lightsaber resistant materials. So the whole cut threw anything idea is pure bunk.

Also Caps shield isn't pure vibranium, it's an adamantium/vibranium composite alloy that's take high level energy blast and repeated strikes from guys with class 100 strength. In the rare instance that it is broken it tends to be by cosmic level baddies that can punch apart planets and/or bend the building blocks of the universe to their will.

So yeah I'm sticking with their being no evidence to the theory that a lightsaber can cut threw Caps shield. And that any suggestion to the contrary is nothing more then Star Wars fanboyary.
