Some swordcanes are Awesome, but Impractical. Many have short, flimsy blades that are very slow to draw since you have to manually screw the handle off, which can be a dangerous waste of time if you actually need to defend yourself. You're generally better off just bludgeoning someone with a normal, solid cane rather than use those canes. However, other examples are built more practicably. Just don't bring one to an area where they're illegal!
