Probably my Gillette Old style followed closely by my Gillette New... "Deluxe" I think it's called? It looks like an aggressive version of the flat-bottomed new-style.
The Old style (1905 first production year of the single ring I think) is essentially a horizontal shavette. It has some safety teeth in the form of a toothed comb, but there's no blade gap - it's just a blade resting on the safety teeth. I think they were possibly a bit generous in calling it a "safety" razor. Their idea of safety seems to have been: "You >>probably<< won't cut yourself deeply enough to open an artery." Lol...
