My original reply to Derren was pointing out the fallacy that in the situation he provided that implied that a shortsword would be potential more effective than a Two-handed sword.
I understood what you were responding to. You were right, the short-sword is not potentially more effective. However, I was responding to your claim that conversely, the two-handed sword was potentially more effective than the short-sword in the same circumstances. On that point I believe you're wrong, and you have provided no evidence why this is so. A two-handed sword being wielded in a half-sword manner (one hand on the hilt, one hand on the blade) is going to be about as long as the short-sword (thus basically the same reach). Therefore, no advantage for the two-handed sword. One might even make the argument that since the short-sword can be wielded one handed in this situation, it's potentially more manuevarable than the two-handed sword (even when wielded in a half-sword manner). However, I'm more of the mind that it's a wash. But my previou statement still holds true.
Effective: Yes.
More Effective: No.

Only when you are not comparing them for a job at hand. If you are trying to split boards, both a hacksaw and a hammer could do it but the splits created with the hacksaw would be cleaner and more accurate.
Also a shortsword:two-handed sword isn't a hacksaw:hammer comparison. It is more a 6" hacksaw to 4' handsaw comparison. I'm not comparing a shortsword(a thrusting/cutting weapon) and a mace(a bludgeoning weapon), I'm commenting on a comparison about two thrusting/cutting weapons.
That's a good point.
I wasn't trying to say that.
...
I never did. I think you are confusing me with other posters.
Nope. No confusion.

At that point every weapon starts having problems, and a half-sworded two-handed sword would still be potentially more effective than a shortsword.
