I decided to make my own wolverine claws for Halloween. The facial hair is up to you.

1). Cut 6 of the attached files out of a sheet of steel on a laser cutter or something like that

2). Grind down any sharp edges

3). Cut out two 3-inch long segments of 1-inch diameter steel tubing

4). Grind down any sharp edges

5). Weld three of the claws on each length of tubing

Make sure that the spacing between the claws is big enough for your knuckles.

Edit: Be sure to test the spacing on both of your hands. Apparently, the knuckles on one of my hands is larger than the knuckles on the other. I wrapped electrical tape around the bottom of the steel pipe to color-code it to each hand since the claws I made weren't ambidextrous.
