Forging the Viper Fang Knife
I was watching the movie chronicles of Riddick and seen him using some very interesting blades. I did some research and found out the knives used in the movie are called Ulak. Of course I didn't make the knives from the movie, I forged my own version of the knife using a 24 inch RIDGID pipe wrench hook jaw. This was a very challenging knife to forge but I'm very happy with the end result.
