The Rein Borste (or Rein Dachs w/ badgers) boar shaving brush is “Handmade in Germany” by a Bavarian company for over 100 years. The Superior Shave is the sole US importer. They’re offered in several hair types, with various handles available for each type of knot. In all cases, weighing, gathering, forming, and gluing the knots is a handmade affair by skilled craftsmen who apprentice for three years in a dedicated school of brush making.

True Germans Gonna German
Ahh, the Germans – if you can’t love how anal they are, you need to travel more. No need for ‘police lineup’ images due to the strict control of production of this boar shaving brush. They’re remarkably consistent from specimen to specimen.
A European Union firm produces this handle (these folks don’t make handles, like Simpsons for example).
