I remember the Gillette Blue Blades. One use and you dropped them in the slot in the medicine cabinet.
I also remember the necessary styptic pencil to stop the bleeding, and an alcohol based after shave to kill the razor burn.
I like double blade disposable razors.
I haven't used a styptic pencil since the first week I switched over. Alcohol based aftershaves are also old school. There are tons of soothing aftershaves that don't burn at all. The better blades don't burn at all,
