I see you joined this June.

If you thought that shaving with and maintaining a straight razor is as easy as changing the cartridge in your Mah3, you are wrong. It isn't. That is the reason that straight razor was defeated by DE razors and such.

If you really want to shave with a straight razor, you have to invest some time learning the skill of sharpening it.

There is alternative, though. You can get a replaceable blade straight razor like the Shavette from DOVO, or the Feather straight razor. Both will give excellent shaves.
