Not a safety razor

First version of a "one part" razor using standard blades.
The blade is hold by the spring structure of the handle.
The razor can rest on a flat surface without the blade touching said surface.
Although it looks like a safety razor, this is absolutely not a safety razor: the blade is not protected in any way. Do not even think about trying this razor if you don't already have a strong experience in using straight razor, shaving with a rusty knife or a viking axe.

A better design will follo
