Im a little crazy about shaving. Though i dont always shave or shave often but when i do im a bit anal about it. First off i use an old school safety razor, but the three half blade kind rather than a single double blade. I also only use the razor for about 3 shaves then replace it. I also remove clean and dru the individual blades between shaves, oil them and store them outside of thr bathroom to avoid humidity. I even rotate the blades between shaves.
In case you arent familiar with half blade safety razors i attached a picture.
