Maybe a singled-edged razor like the Supply? I've taken this razor in my carry-on a couple of times.TSA agents are highly variable. You can bring a DE in a carryon but they are more likely to search your bag, etc. Expect questions even if you don’t carry a blade.
This means that I am back to carts (UGH) for air travel as I am a 1 bag traveler.
That's what I'm talking aboutIf you bring a de in your carry on, just take the razor apart separating the head from the handle and it will be less likely to get you flagged as a razor and investigated for a blade in it or not. I've done this for a while now and they've never even looked at it. I wrap the head and base plate in a napkin as well as a second base plate and place it all inside a pill bottle along with the handle. This way it looks nothing like a razor at all. No T shape to look for. A brush goes into a pill bottle as well with some holes drilled in it. Soaps in small screw top containers. A plastic salsa bowl to lather in and a small bottle of aftershave balm in the dopp bag as well.
Nice idea. Now, I just need to find travel cases for DE razor and shaving brush and a razor roll for my straight razors.For pasted balsa I use necktie boxes (Amazon) to both protect the balsa and keep the paste where it belongs.
