A cane makes an awesome self defense weapon, as well as it's intended use as a mobility aid. It works as camoflage to make you appear less threatening (especially to the federales) and can also be used to carry additional gear if needed.

Canes are allowed on all airplanes, as long as they are just canes and not sword canes. A cane can give reach to keep a knife fighter at bay, especially when used two handed to block and poke. Lastly canes can be had for well under $20 at any drug, or big box store.

Take Care and Stay Safe.
