I have been using boar bristle brushes since the mid 70's when my mother bought for me an Old Spice mug and brush, I had acquired a straight razor from my barber back then. Back to the brush, I do not hang any brush upside down, they all dry sitting on their handle...but I make sure after I shave to rinse the brush under cold water and towel dry it and never had a split handle be it a sheapo or expensive brush.
