I don't get it, either. I made a bunch of changes to Quickdraw to remedy this problem several years ago:
Quick Draw [General, Fighter]
Prerequisite: base attack bonus +1
Benefit: You may draw a weapon, retrieve potions from your belt, anything from a Heward’s Handy Haversack, or any other retrieval action that typically requires a move action as a free action. You may draw a hidden weapon as a move action and may make a full attack with thrown weapons.
Synergy: If you have this feat and Weapon Focus for a particular weapon, you may sheathe it as a free action as well.
Normal: See page 142 in the PHB.
So, you can basically draw anything that would have taken a move action as a free action with that revision. Makes Handy Haversack even more handy. Feat synergy is something I made up for two feats giving an added bonus when a character possesses both. Probably self-explanatory.
Love it. I always go with an extended ruling of this feat too. (If something normally takes a move action to retrieve, now a free action).
That way the feat can be usefull for more people then just the jarlaxle/daggerthrowing builds.
