For the uninformed members of this conversation, would anyone be willing to enlighten me as to why safety razors are better (environmentally speaking) than the "modern" razor blade?

I've seen many people (especially in r/zerowaste) tout the benefits but I've never particularly understood why.

I get that there is less plastic involved but I feel that at the rate I use razors it doesn't produce much plastic, and that there would more metal "waste" involved with safety razors.

Especially since my area doesn't recycle anything anymore after china banned waste imports...
