What are the Four Treasures?
Hmm, odd question. The Four Treasures of Fudebakudo were originally the same as the Four Treasures of the Chinese scholar — the brush, the inkstick, the inkstone, and the paper. However the pen, which contained its own reservoir of ink, was gradually adopted, replacing the brush as the first treasure and handily freeing up the next two, namely the inkstick and inkstone. These were replaced with the sword and the credit card and beer. These are now regarded as the five definitive Four Treasures of Fudebakudo, although there may be others.
