Dagnabbit! The one thing I was safe from was a brush AD. The pure badger I had was perfectly functional, better brushes were expensive enough to make curious experimentation purchases prohibitive. I had my brush and I was happy with it, freeing me up to acquire new and interesting blades, razors, soaps and creams.
But I just HAD to pick up a <$20 boar brush. And fall in love with it. Now I want more.
