[SW] How could Vader block with his hands?

Okay was his hand made of some really bad ass metal (like Mandalorian Ore) or was he using the same trick Yoda used to block Force Lightning with his hands?

The armor isn't ornamental, it's based heavily on traditional Sith Armor from the old days. His armor is generally blaster resistant and only the biggest guns or a lightsaber will work on him, if he let himself get hit at all. Combine that with the Force and you got a nigh invincible boogeyman.
