The sheild was made for dead on attacks which is why a swinging sword will break it but a impact from a hammer wont

Even if the hammer is as heavy as a f**king NEUTRON STAR

Its 47 pounds

Bruh

Haha

Seriously that sword absolutely obliterated that shield

but tony made cap another shield that wasn't vibranium because he got rid of it in civil war, remember?

when Tony said his father made that shield after the fight

Plot Twist: the sword is also made from vibranium
