You can use the Weapon Finesse feat to apply your Dexterity modifier instead of your Strength modifier to attack rolls with a cane-sword sized for you, even though it isn’t a light weapon for you. You can’t wield a cane-sword in two hands in order to apply 1-1/2 times your Strength bonus to damage.
Its a part of fictions background so I though I had better stat it up. In game terms the actual weapon is a slightly expensive rapier.
The high cost is due to the difficult nature of having the catch and so on work easily as well as hiding the fact it is a sword. Removing it from the cane is the equivalent of drawing a weapon. Most cane-swords used by nobles are masterwork, while the normal type is often used by the gentleman class.
Special: Rogues are proficient. Note despite the similarity it is not a rapier and rapier feats do not apply. Whilst in the cane a DC 22 (24 for a masterworked one) spot check or a DC 16 (18 for msw) search check reveals it for what it is. Obscuring the joint (tucked under the arm for example) prevents such checks. If it is being used for walking then a DC 18 (20 for msw) listen check may also be made (the damn thing tends to rattle). Conceivably better disguises are available but would cost more.
