Since my last tool that utilizes razor blade was kinda lame, I've decided to make it up. This time something that really works fine. A tool that will help you cut the insulation of the electric cables. Just slide the cable between two razors and rotate 180 degrees. Perfect thin, delicate cut, and you can remove the insulation easily. For cables between 1,3 mm up to 4 mm total of the diameter. Quite decent print, under 40 minutes (all elements), and razors are mounted by two printed plates. Quite safe after assembly. Utilizes two standard razor blades.
