Blue
Ravenous Bugblatter Beast of Traal
To me, a sentient item has some sort of soul in it. I wouldn't picture you could just realign it. Generally, I think you'd need to replace the spirit,but sicne the spirit is so tied in to the rest that might require destroying it, or at least loosening (and therefore weakening) the magic.
But that's just how I view these things, there's nothing official even back to AD&D about changing the alignment of a intelligent weapon.
Actually, as a DM I'd have them get the weapon back and it's the spirit tied to it has some kind of ongoing aversion therapy going on,so that every time it tries to be evil (including enjoying the bite of flesh) it screams in pain, ending in whimpering.
