So...that means Wolverine can stab him, right? Because Adamantite is stronger than steel. Correct?
Not really, it's just a nickname. Wolverine couldn't stab Superman.
Faster than a Speeding bullet too!! They are just expressions/nicknames. Obviously he's faster than a speeding bullet, he can run from Kansas to Mexico and back and you wouldn't even know it. If you want it literally, just call him Superman, or extremely tough and fast man.
Adamanium might be able to penatrate Superman's skin, but you would need a lot more force than Wolverine's arm could manage, perhaps an ultimate fastball special, fans know what I mean. It has never been determined what can penetrate Superman. Guess it depends on who's writing it.
I don't think Wolverine could stab Superman. The name Man of Steel is just a nickname that was acquired through the years. Just like Superman is able to fly, but when the initial comic came out, he could only, leap tall buildings with a single bound, and is stronger than a locomotive. Of course, now he can fly and is MUCH more stronger than a train! hahahahah. So even though Wolverine is cool, I hardly doubt he could stab Superman...not that he would of course. =)
