A smart black walking stick with a silver handle looked incomplete without a silver ferrule. This has a thick dimpled base though, as the stick is for special occasions, I don't anticipate a great deal of wear.

This ferrule is different.  It is actually a cover over a standard rubber foot and is therefore more practical.  The rubber foot can easily be replaced when it wears low.

The glass head on the cane had a crude copper brass mount.  This is now sleeved by silver and looks far more elegant. The foot of the cane has the ferrule cover immediately above.
