Possibly Chinese Pichok?

[RobT]

ausjulius,

Given that "2001" is dot engraved on one side of the blade, there is little doubt that your age assessment is correct. Separatist sentiment aside, I don't know whether or not the Uyghurs by and large consider themselves part of China in the same way that various ethnic groups in US territories (e.g. Puerto Rican Americans) consider themselves but I have seen store signs in Yangigisar which show that Chinese characters (as well as the English alphabet) are commonly used so I don't know if the characters on my knife are a result of government coercion or just the use of a written lingua franca.

Sincerely,
RobT
