The Badass Switchblade from Lara Croft: Tomb Raider (2001)

The Tomb Raider switchblade, which probably exists only as a movie prop. On the left is the knife from the movie Lara Croft: Tomb Raider. To the right is the out-the-front "Tomb Raider" switchblade widely available on the Web, often advertised as "featured in the movie" or "just like in the movie!" The astute observer will note minor differences, such as a completely different handle, switch, and blade, and a ring mounted on the opposite side of the handle. Other than that, it's difficult to tell the two apart.
