So I thought of a couple things that might make you addicted to straight razor shaving.
Feel free to add your own!

You know your addicted to Straight Razors when....

1. You can't wait to shave instead of HATING to.
2. You can't pass by an antique shop without wanting to go look for any "deals" on some old blades.
3. You ban yourself from ebay because you realize you have an addiction. (YES I have done this one)
4. You STILL go to ebay and make a purchase anyways! (Done this also)
5. You look at cups, bowls or anything and wonder if you could use it to make some good lather!
6. SHMBO thinks you are CRAZY for talking about good skin care.
7. From stropping you now count steps one, one, two, two, etc....
8. You end up buying HUNDREDS of dollars worth of equipment to "restore" all your "new" razors.
9. You now know what a Norton 4/8 K is.
10. SHMBO looks over your shoulder when typing this and just LAUGHS!
