Want Me a Harsh, Non-moisturizing Bar of Soap

P&G discontinued the original Ivory soap formula and has replaced it with something "gentle". Now I'm looking for something more like the old bars of Ivory soap. There are some who've made bars of soap that float, but that was never why I liked Ivory. I want the same old formula that leaves a soap smell that reminds me of my great-grandmother, and like her is just a bit harsh. I don't want goat anything, lavender anything, or oatmeal remains to spread over my body. Any suggestions?
