First of all, feel free to disregard the first 2:05 of this video, it is not a how-to but behind-the-scenes footage of this guy's short film. After 2:05, however, you will get a great tutorial on how to make a set of prop Wolverine claw quickly, easily, and cheaply. They are made out of cardboard and spraypaint, and as long as you don't do any closeups on them or require you Wolverine to open his hands with the claws out at any point (impossible in this configuration) they look plenty real. You can literally make the whole set in 10 minutes. It's that easy.
