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

thingiverse

This knife employs precision trapezoid-shaped razor blades, secured by three powerful magnets that effortlessly lock it into place or release it with ease. I meticulously crafted this design using solidworks software, then converted the files to versatile step files for anyone seeking to customize and modify them as they see fit. While I admired the original concept, I felt compelled to enhance its functionality by incorporating magnets, which proved to be a game-changer. Furthermore, I corrected a critical flaw in the original design - oversized holes that compromised dimensional accuracy when printed. To address this issue, I substituted machine screws with nuts on the blade holder, ensuring a more robust and reliable connection.
