Normally my razors dont rust but I put it in a plastic bag while still wet since I was traveling and it got a bit rusted. I was careful for the next few shaves but today I was in a hurry and I didn’t think about the rust and I got like 10 small nicks since I was rushing. Now I’m wondering if I could get tetanus. I got my last shots 9 years ago and I’m assuming that included a tetanus shot but I’m not sure if it was a 10 year shot or less. Help!
