there is a place not far from me that specializes in this... i can't remember the name of it... but if you get off at the
Münchner Freiheit ubahn stop and walk down hohenzollernstrasse until you hit the women's nike store... then bang a right onto that street... within 50 meters you will hit a little store on the west side of the street has a cowboy western look to it... the make keys, sell leather goods and advertise leather tooling on their storefront.
