Morphing Karambit v1 (fang folding knife)
thingiverse
Found this on kickstarter last spring (https://www.kickstarter.com/projects/caswellknives/caswell-morphing-karambit-premium-utility-knife) and did some thorough reverse engineering. You can take it and further refine it from my onshape.com directory: https://cad.onshape.com/documents/957d8ea228106c9ac8672e48/w/59344a520d39c585db87effd/e/58d08893608560d3f4a62df0 !!!NOTE!!! Compare your palm width with the length of the handle grip, then fine-tune the scale of your print accordingly. The connecting pin design is made to use a piece of hard wire (such as a paperclip) to connect parts along an axis. If printed in plastic, it can be easily disassembled on a plane. Tested multiple times without issue.
