No problem! Yeah, these seem pretty solid. You can definitely tell it's not an original when you touch it firmly but at a glance they look the same and they don't even feel all that different, just barely enough to tell. I definitely wouldn't be worried about warping. The hand guard, in particular, feels much more solid.
I haven't tried to match-up Adam's Repro sword with my original Skeletor Power Sword to see how they fit together yet, if they do, so I'll let you know how that goes.
When the repro belt comes I'll be sure and take a picture of my "restored" Prince Adam. Again, I'm trying to be as authentic as possible when tracking down the spare parts but I know that's a lost cause on some figures' accessories, so I'm fine settling for repros for a handful of things. I think they even make the little red clips for the back of Flying Fists He-Man and Terror Claws Skeletor. Pretty sure they make a repro lock for Dragon Blaster Skeletor, too.
God's work, to be sure.
I'm just glad somebody's doing it!
EDIT:
Tried matching up the repro Adam Power Sword with an authentic Skeletor one. They fit, but not 1:1; the repro swords are like a tiny hair smaller but they'll hold together.
