Another question about a knife in a movie.

[SURVIVAL&WEAPONS]

So today i watched the movie "lets be cops" and in multiple times durring the movie, one of the "fake cops" pulls out a OTF auto. I believe the character is "ryan O'malley". Now i dont know much about autos, i was womdering if anyone who watched the had a hunch that would be cool. Me being ignorant to autos and more specifically OTF's i thought in my head microtech. (I generally temd to stay to manuals and a/o.) so pretty much i was just wondering, seeing the knife and not knowing is kinda bugging me now.
