Numb3rs knife

[D'ohboy]

So about thirteen minutes into season 6 episode 10 David uses a knife for a little impromptu dry walling.

I think it's a benchmade and from the logo, which is admittedly hard to read, a Mel Pardue design, but the blade shape and length look wrong for a Griptilian. Anyone have any ideas as to what knife this is?

could it be the presidio?

Looks like an ambush, sort of has that almost recurve to it. Blade length looks right too. Dunno though, it could be a tanto grip.
