This blade is modeled after the saber claws used by Riddick
Step 2: Handle
Add these pieces to both sides of the handle of the blade. The blue slotted connector closest to the blade can be difficult to get in. I suggest wedging it in between both silver rods on both sides and then snapping the parts together.
Step 3: Finished
Enjoy your new k'nex saber claw. (id suggest making two of these, its much funner that way) =:^b
