Retracc: The Retractable Karambit Knife [Now With Magnets!!]

This knife uses regular trapezoid shaped razor blades, with 3 magnets allowing it to lock closed or open.
I designed this in solidworks, and converted the files to step files for anyone who wants to modify it.
I loved the original design, but I felt it needed magnets and all the holes were much too oversized when printed dimensional accurate, I also didn't have any M2.5 hardware and I don't trust machine screws threaded into plastic so I added nuts on the blade holder.

This is a remix of a design by corrugatorsupercilii that has been removed from thingiverse, you can find it reuploaded to cults3d here: https://cults3d.com/en/3d-model/tool/retractable-cat-claw-box-cutter-corrugatorsupercilii
