Currently there exist a few weapons for the explicit purpose of allowing players to gain the benefits of parry AC while holding a weapon in their offhand, the issue is that despite this they're not fulfilling their purpose.

1) These weapons can only ever be found and not crafted
2) They only allow half of your parry AC to be gained (3 instead of 6)
3) Two-weapon fighting is required and it'll still cost you 1 AB to wield them, even with 3 feats invested
4) They have no enchantment bonuses to speak of and usually no-damage as a modifier

I'd like to suggest the following
1) Allow Swordbreaker to be crafted
2) Increase the parry AC from 50% to 100% and allow players to gain the full benefit of their parry investment
3) Make all weapons with the Additional Property: Parry AC also carry No Damage

I think this would make them an appealing alternative to shields for characters who want to invest 3 feats and 30 skill points as otherwise these items have too many requirements compared to just not holding anything in your offhand, or merely wielding a shield.
