Here are my take on some cosplay Wolverine claws (Logan style). I've been looking to create some Logan claws, just in case I decide to go as Old Man Logan this year, but could not find exactly what I was looking for. Other claws that I have found were either unfinished or too long for my printer. So I created my own claws: double bladed, come in 2 pieces with pins to align them when putting them together, and a simple handle. Depending on the size of your hands, you can scale them all up or down to fit you better.
There are 3 different claws: A, B, C. These go from pointer to pinky. Why 3? Well I didn't want any gaps between the claw and my knuckles, so I tweaked each claw to fit better. I have also angled the notches in the handle so that the blades will splay a bit. Looks cooler and easier to get your knuckles into the claw assembly.
As you can see in the picture, I covered the handle with black gaffers tape: one to hide it, and two to soak up some of the sweat from wearing them for a while. Let me know if you have any questions.
