For the last several years, I had reverted to very simplistic wet shaving (one soap, razor, brush) but am returning to the hobby. In that time, my Crabtree & Evelyn pure badger brush has seen better days. The handle has earned a ding and chip patina from much clinking on the sides of a shave bowl. A once fair badger knot has shed enough hair it looks like an old possum. Yes it is functional, but it has lost much in its decade of age. I'll probably not toss it out, but it will be relagated to the back of the line at a minimum. What has caused you to toss out a brush? What made you keep it after it was beyond its prime?
