When I reach the required age, I plan on having a swordstick, which, provided I do not topple over in the attempt, I shall brandish at any ruffians and ne'er-do-wells that night attempt to accost me. Or Professor Moriarty, if necessary.

I suspect the legality might be somewhat dubious, but I'm banking on a blind eye being turned here in Spain.

But having a lethal blade concealed within a walking stick would make it feel more empowering, and less psychologically belittling, I feel.
