For the Repaired Weapons the normal ornamental Mage-like Staff gets Dex Bonuses and the Martial Arts Quarter Staff gets Focus Bonuses which seems backwards to me. I would think you would be more likely to actually smack things with a Quarter Staff not a Delicate Mage's Staff.
Also I am not sure about this one but the Sword Grip seems to be unused for anything but I THINK it was meant to be used for the Two-Handed Swords as opposed to the Pommel (which would make perfect sense) yet the Two-Handed Swords still call for the Pommel.
