These are the saber claws from The Chronicles of Riddick. These were made by Master Cutlery, and i have to say they did a great job. The only things that arent accurate are the color of the blades and the grips. In the movie they look like they are silver like a regular blade, however it could just be the lighting. In the movie the grips look like solid rubber. These are wrapped. None the less these are great props. They were only 25 dollars. So I naturally bought two sets of two :D One set to mess with, the other to display.

UPDATE:
I have started making plans for a Chronicles of Riddick: Dark Fury knife. Hopefully i will be able to get to work on it soon!
