Here is a challenge. How many of Marvel's good guys carry unique weapons? Now, I admit nothing is unique: Thor has a hammer in several dimensions, etc. I'm also not bothered if they aren't actually weapons, just things they carry and use to do good deeds. Be interesting to field a team that each had a unique weapon. Is it possible?
Captain America (Shield)
Tigra (some kind of brooch thing)
Black Knight (Soul sword - not what he has now)
Andreas von Strucker/Swordsman- His sword.
After Baron Helmut Zemo murdered Andrea, Andreas flayed Andrea's flesh from her corpse, tanned it, and made it the hilt of his sword. He thus retains his mutant power but now he channels it through his sword
