Yes, with a minimal investment in a good brush and Merkur razor + blades a couple years ago, I've already saved by going the double-edged way plus the shave is way better.

Only real problem is that I still haven't figured out how to do carry-on only and keep blades on me.

I've only ever had one TSA agent realize that I didn't have a cartridge razor in my dopp and confiscate my blades. Since that happened (but before I became an enormous beardo), I've brought only the bare minimum blades needed for my trips packed edge on to the x-ray scanner and left the butterfly in my shave kit but opened to show it was empty.

I imagine a safer and less obstreperous way might be to just buy an injector razor for when you travel.

I use Harry's for the TSA and DE Safety for day to do. And because I only travel once every 6 weeks, I am okay with it.

You have a beard, and you carry DE blades on board, detailing how you hide them from TSA scanners on a public forum? Had any "longer chats" with TSA in an airport windowless room yet?

I usually disassemble my Merkur before it's in my toiletry, but have a spare blade or two in wax paper floating around-- it doesn't seem to attract attention if it's not inside the razor assembly...
