Bruise, Thanks for the link to a US source for an interesting knife!
Red Flower's analysis of the writing on the knife brings up an interesting point, related to the "Can This Destroy America" thread in which the starting essay has a thesis that multilingual societies destroy themselves.
China has been multilingual for millennia. However, a few thousand years ago the first Qin (?) Emperor, the Emperor in the movie Hero, unified the written language. (Largely by killing everyone who disagreed with him. He buried lots of scholars alive, etc. ) Since the uniform character set was ideographic and not based on the pronunciation of words, people of all dialects could read and write it, even though they could not understand each others speech. This uniformity in writing has helped to unify China and facilitate communication for many hundreds of years now.
Even now Red Flower can understand many of the Japanese characters, although she cant speak Japanese. A few years ago the Chinese government simplified many of the characters, so characters written before the simplification, or by overseas Chinese people, or Japanese, may look somewhat different. To most Chinese people the difference between the simplified characters and the traditional ones is as unnoticeable as a difference in fonts to readers of the Roman alphabet.
