Culmak Shaving Brush Drier

Place the brush upside down to aid drying? Knot on the prongs? - complete and utter guess...
Well, yes ... but that would pull the hairs together making a damp core. I suppose the brush could kinda balance like on an angle cradled by the prongs but even that would not gain anything over and above just sitting the brush on its base.

I like to think you actually put the brush into the cavity and place a crystal in the prongs!
