I just started watching The Defenders the other day; I'm pretty amped up about it after just finishing the third episode.
I didn't know how powerful Iron Fist was when he summons the iron fist until I began watching Iron Fist's series. So far from what I've seen it looks like the iron fist packs Saitama level strength as he can punch through a samurai sword and shatter it in pieces while sending the person who is wielding it airborne. Hell, in one episode he punched Luke Cage, who is literally harder than concrete, hard enough to make the guy flinch in pain as he when airborne.
But anyways I was wondering, is Iron Fist's fist strong enough to shatter adamantium? Say if he was to ever fight Wolverine and during the fight Wolverine tries to claw him but summons the iron fist before he does would he be able to shatter Wolverine's claws if he punches them on time like he did with the samurai sword? Or perhaps maybe just cause them to bend at least?
