They make straights for ears, but don’t use it yourself.... https://www.aframestokyo.com/machida-tadashi-56mm-takefu-v1-blade-aural-ra561.html
I’d like to have one just to see how to hone/strop it (Do you even strop these?). But not at that price. I see them on Yahoo.jp once in a while, usually in a lot that I wouldn’t want anyway.
I don’t think of them as archaic any longer. I just think of them as simple and beautiful - art objects that can be used daily. Straight razors have a sublime quality. They also give the best shave of any known method of shaving. I can’t conceive of shaving any other way now that I have converted. Never a nick, never a weaper or razor burn. I can’t say that about a DE, cart or electric.
