Welcome aboard. It is awesome you can share that with your dad. Mine still doesn't understand why i would want to shave with a DE. He says it hurt like hell scraping his face with his (which i now have) every day when he was in the army. I don't know how to break it to him that the razor wasn't the problem but really just his shoddy technique. he is a dedicated electric man now. :( I am going to work on my little brother though!
I hope you enjoy the community! also, i just had my first SE shave with a Gem 1912 yesterday. wow. you are in for a surprise. its something else.
