I don't know of any specifically left handed models, but the Spyderco Endura I carry is fully ambidextrous and can be carried tip up or tip down. (There are four mounting points for the pocket clip.) The waved version can only be carried tip up, but is still reversible for left and right. The thumb hole and back lock are ambidextrous by nature. It's VG-10 rather than the steels you mentioned, but I would put VG-10 somewhere between 154cm and S30v for quality.
