What kind of knife is this?

I recently purchased a knife from the Army/Navy surplus depot and I have been trying to research and find out what kind of knife it is, but to no successful end. It has a 7" black double-edged blade, 2" tang without a bayonet-style muzzle ring, and a compressed-leather handle. It bears the manufacture site (Taiwan) as well as the number 33080, the word "Fury" and a letter 'A' inside a circle on the blade-oriented side of the tang. I realize it may be of no astounding origin, but I would still like to know.
