You can use any walking stick as a defense weapon.

Forget the caveman swing. Grasp the stick in both hands, and push it towards your target. Think thrust, not swing. Accompanied by a loud yell, this is effective on people and animals.

If it's collapsible, collapse it. Tends not to break this way.

Guaranteed, you shove the end of a stick, pointed or not, into somebody or something, they will not want to play after one or two pokes.

Thrust and holler.
