The sword cane itself is a 1-handed weapon, so it seems really unlikely that it would be hidden inside something "about five feet in length." And it can be drawn as a swift action, which implies more of "push button, disguise drops off" than "reach up to top of staff, pull long-ish blade out."
Plus, the combat scabbard exists. It's a holder for a one-handed blade that, when used in combat, deals the same damage as a club.
I would lean heavily towards the "club" stance, personally.
