clingon knife?

yesterday my mom, dad, and I went to my aunts house to wait for the guy to shut the gas off(my aunt had already moved to tennesse) and afterward we went up to the attic cause my mom still had stuff up there that she left when she moved out. well, we went up to the attic and foun a bunch of swords and wepons that her son jeremy had left behind. this was one of them. we thought it looked like a clingon knife.
