I discovered the Kanzy type razor with replaceable blade through my son and I found it very valid, practical to use and convenient given that the price per blade is much lower than the plastic ones with multiple blades. The only downside is that the razor we purchased did not have a package to use when not in use. Not content to leave it in sight or in the drawer with the blades exposed and the risk of cutting yourself, so I created this simple blade protector. After using the razor and rinsing it, you can use the same screwing mechanism that is used to replace the blade in order to insert the blade protector which also allows you to leave the razor in a vertical position. I hope that this solution can also be useful to others who have purchased a razor of this type.
