I want a big guy with a big sword to block the small swords!

Guarded 1 action Feat 1

Fighter Open Stance
Requirements You are not wielding a shield and you are wielding a melee weapon.

If you time it right, a sword is a shield. You can now take the raise a shield action using your sword to block incoming blows. Your AC does not increase, but the weapon functions just like a shield for using shield block feat.

Thoughts.
