Well I guess I'm just a badass bitch, because I have a real longsword and you don't, Mr.Thinks girls don't know how swords work.

A sword fighter doesn't have much strength to give the very tip of their sword, only the momentum carried can really empower the full extent of a blade. I figured about half a foot of the sword was under the shield, and if it got caught between the shield and the ground; (highly likely, given how low the attacks and blocks were) Sigurd would feel a shot go up his arm, and he'd need to yank his sword out. It's not mortally dangerous or anything, but how you described its effects, I see it doing more than just stall for a split second. I never meant to disarm him, however the strike has enough weight and pincered force to bend the average sword, and he'd feel that more than you described.

I think if the longsword struck the gladius, it'd stall for longer. The momentum of Sigurd's swing would've been lost when he decided to try and slap dat fine ass Iolanthe possesses. However the 'I can interpret it however I want' rebuttal about key parts being omitted... if that's true, then I'm sure the gladius stabbed in to Sigurd's wrist, that was a key attack, it's effects omitted from your post.

For Sigurd's punch to be effective, his shin should be facing Iolanthe, and not the blade of Hyperion, which is coming towards him on his left side. The fact that her sword pierced through his boot and cut him already means that armour should not suddenly appear there to conveniently protect him the second time. It was mentioned in Iolanthe's post, that she angled her spear so that if he progressed, it'd cut his ankle, but if he stepped back far, it'd cut his knee, even further and she'd be spanking him like the naughty boy he's been.

Again we're probably going to have to wait for [@Drifting Pollen]'s verdict.
