For such cases, I plan on buying the "Unbreakable Umbrella." Watch the videos and you'll be hooked! Take it to church, on a foreign mission, on airplanes, in the White House, wherever you want without a single funny look.

That is one way......and this is another;
Being an Irishman, I take a Shillelagh.
I have studied and practice, Bataireacht, a form of Irish martial art, using the iIrish walking stick or Shillelagh.
"The actual 'bata' or stick used for bataireacht is referred to as a "Sail-Éille" or phonetically in English as "shillelagh". The word "cudgel" is also used in period texts. Traditionally, blackthorn, oak, ash and hazel were the most common types of woods used to make shillelagh fighting sticks."
"Modern practise of Bataireacht has arisen among some practitioners from a desire to maintain or reinstate Irish family traditions, while for others a comination of historical and cultural interest has lead to their interest in bataireacht. Practitioners exist in Ireland, the United States and Canada, in movements started somewhat independently of each other. Bataireacht is also gaining popularity among the non-Irish, especially in the United States, as a form of self defense, since a cane or walking stick can be carried easily in modern society. As is the case with most martial arts, multiple versions exist."

Who would deny a man getting on a plane, his walking stick? I flowen into such bastions of anti-gun America as New York, with out a second glanse at my Shillelagh.
Below are pictured a couple of stout, oak Shillelaghs that I have made and carried.
