If it is an OTS with about a 2 inch blade and a black rubberized handle then it is most likely a Chinese copy of a Dalton Callifornia Special. Or possibly a real Dalton. Is there a D.C.C on the left bottom of the logo and U.S.A. on the right bottom? Also is there a tiger in the logo with 3 lightning bolts below it?
