Draw or Sheathe a Weapon
Drawing a weapon so that you can use it in combat or putting it away so that you have a free hand requires a move action. This action includes activating or deactivating the weapon. This also applies to weapon-like objects that are easily accessible, such as remote controls and most tools or sensors you can carry and use with one hand. If your weapon or weapon-like object is stored in a pack or otherwise out of easy reach, you must instead retrieve it as a stored item before you can use it (see Manipulate an Item below).
Exception: If you have a base attack bonus of +1 or higher, you can combine drawing or sheathing a weapon or weapon-like object with moving up to your speed as a single move action.
