Does anyone know the make or model of Nick Randall's knife?

Cold Steel Tanto, like in this 1980s magazine ad - https://i.imgur.com/K2UFK2O.jpg - except with a black finish (I don't know if that was a factory finish or if it was applied by the prop department).

They still make them - https://www.bladehq.com/cat--Cold-Steel-Tanto-Series--857
