Rambo or Similar Movie Scene?

[Critter]

For an upcoming PowerPoint presentation, I am looking for a image from a scene in a Rambo movie (or similar) showing one of those rather spectacular, if not particulary practical, Rambo (or Rambo style) knives. Something along the lines of http://stevensthole.com/pics/rambo-knife.jpg, but somewhat larger in size and better quality. If anyone can point me to an image online or can email me one I'd appreciate it. You can email to: rambo(at)equipped(dot)org

Thanks
