Spyderco Police in stainless Steel and my guess, a Supertool 200, seem a little bit like rounded edges on the handle
Yeah, It's definitely not a wave or any of the Leathermans with outside accessible tools. It looks kinda chunky in one of the shots so I think it is thicker than a rebar. And the movie came out in 2013, so it was probably filmed in 2011 or 2012, so it would definitely be a tool at least that old.
Awesome catches! Not a bad movie, I saw it a while ago. 
Yeah, I was surprised. I like Statham a lot, but he does have about a half dozen very forgettable movies. I assumed that this would have been one of them because I had not seen it before. But it's pretty good. Statham's Parker is not nearly as good a Mel Gibson's take on the character, but it's a fun movie.
