Two distinct types of walking canes

They can be classed in two distinct categories :

1. Gadget canes
   These are ingenious and might conceal for example a sword, a flask of alcohol or a cigarette case.
   
   
2. Fashionable walking canes
   These are more refined and the most intricate and most valuable part would be the knob. It is the knob that gives character and originality to the walking cane.
