Here's a long shot if there are any CSI fans here. In the ninth season episode "Descent of Man", near the end of the episode, while he's out in the desert, Dr. Langston uses his pocket knife to move a tortoise shell. Although it was only a quick shot, the shape of the blade suggested it might have been a Laguiole-style knife. Because of a personal interest in French knives, I wonder if anyone knows what knife was in fact used or if anyone may have a screencap of the knife. Thanks.
