Sword Cane: This slender light blade lies within a wooden container that serves as both its scabbard and hiding place. You can draw the blade from the cane as a swift action (or a free action if you have the Quick Draw feat). An observer must make a DC 20 Perception check to realize an undrawn sword cane is a weapon rather than a walking stick; the DC decreases to 10 if the observer is able to handle the weapon.
