Yo Homie, is that my briefcase?!

 

[Synov]

I think I saw a knife like that in the display case at a truck stop. You'd think Tom would have something classier, like a Sebbie.

To be fair, the original was Jean Reno's knife, not Tom's

It was indeed a prop knife made by John Browning, who also made the Crocodile Dundee knife. The shape of the blade resembles a dive knife and the resin handle seem to be inspired by the Puma lockback.
