Description
Universal razor blade holder using double-sided tape.
I have tested it on 3 different razor blades; it should work in almost all cases.
In case it does not work for you, leave a comment with the 2 dimensions from the image below after measuring your blade, and I will create a new version.
Example:
Upper part: 48mm
Lower part: 30mm
