I don't think there's anybody on this forum so you're the guru. Aside from having a bit of a knife fetish, as an (ex) shipwright I've sharpened any carpentry tool you can think of going back to the ones they used to build the Ark with. Strangely enough I don't have any desire to start straight shaving. I'd be quite happy for a barber to do it but I always want to get out of a barber shop as quickly as possible so that's not going to happen in a hurry. But doing it yourself just looks a bit clumsy with all that skin stretching.
You should try SEs. A lot of straight shavers appreciate SE shaving and refer to them as straights on a stick. Which is historically pretty acurate actually.
