PvP weapons

Ok it the answer is some where in here i cant find it. Im wondering, who do you get new PvP weapons? Can this be done? or do we have to use the same ones as when we made the charcters.

What weapons you are able to use is determined by your attributes. Need at least a 9 (last time I checked) to unlock weapons/items for that attribute. But this is when you create a character. Also, you are able to pick two weapon sets, so that should be more than enough. Just delete and recreate when needed.

I've unlocked new grips/whatever while identifying magic items, I don't remember which but I remember identifying a salvageable item and unlocking a grip or something.
