I'll tell you the only way I know how. In Kyoto, Japan, there is a street named Senbon Dori. Walk on this street southward (it's very important that you be walking, not riding a bicycle or driving a car). It won't be long before you see an elementary school on your right. Across the street from the school is a decrepit car mechanic shop. Knock eight times on its door to the tune of the Polish national anthem. The door will be answered by a Japanese man in a muscle shirt with a sleeve tattoo of a pine tree on his left arm. He will ask you "where does the sun never set?" You will answer, in Polish, "upon the righteous man's beard." At this point you will produce the money, and he, the blade. That's the end of the transaction and you can leave. Also, make sure you show up with a beard, or you might get killed.
