Technically it wouldn't work. One of the weapons is not a legal weapon when it completes the strike.
That's why they both instantly dissipate. Temporal feedback loop.Actually, BOTH the weapons aren't legal when they complete the strike, which means neither effect should activate. Which in turn means both weapons were legal when they struck.... Aaaaaaaaarrrrrrggggghhhh.... paradox!!!!

Yeah but really this one should be Rule of Cool'd and both people should just take it. That would be a great story.
As to point A, you misunderstood what I meant. I meant that if I want to hit your shield, it is nearly impossible for you to get an arm in the way of that attack. You might dodge it, but getting an arm in the way is pretty close to impossible (one is holding the shield and the other is presumably partially covered by the shield and holding a weapon).
As to point B, "Shatter" is a very quick word to say. There is a point of no return where I can be certain I will block your swing but before contact has been made. I have no doubt that timing that point of no return will be simple for experienced players.

I don't disagree. I just think that blocks are rarely static. Most blocks that I have seen involve swinging a weapon with force roughly equivalent to the force of the other weapon (if for no other reason than to prevent the attacking weapon from pushing through). You pretty much have to swing your weapon in order to block, unless the person attacking you is specifically aiming for your weapon (which only makes sense if they are also trying to Shatter/Disarm your weapon).
