Not sure about that. I generally do 2 passes with both cartridge or safety razor.
I had started with safety razor, then moved to cartridges for many years, and now am back to safety razor, with a better razor.
Safety razor probably take a couple of extra minutes since I'm slightly more careful with it than am with cartridges.
I read that it is hard to shave the upper lip area with one of these.
I fill up a coffee can with the used blades (it takes years to do so) and have a place I can take them locally.
Edit, to add: terracycle also takes a lot of other recyclable items that you can seldom-if-ever recycle curbside, like guitar strings. Most big cities have music stores that have partnered with the program and you can drop all musical instrument strings there. Here are all of their programs for those interested: https://www.terracycle.com/en-US/brigades
Shavettes are extremely affordable, like $10 for the base. Unlike a "real" straight razor, shavettes never require sharpening since they just use standard disposable single-edge blades, or a double-edge blade split in half.
Shaving with a double edge instead of using a disposable is comparable to preparing your own dinner rather than going to McDonald's. It's a skill, it takes time, it's far for economical, there's a ritual to it, and it's enjoyable. It's also a uniquely positive masculine thing (and I think that that does matter) and one day I can pass the razor to my son or grandson.

But even with a good brush, which is as essential as a sharp blade for that kind of shaving, it just cannot compete in my opinion. It takes longer and is more bloody. Boy did razors made technological improvements, I think the plastic ones really can compete today.
It looks easy how barbers do it but it is another thing if you do it in front of a mirror.
But I do have to shave my head and I just can't figure out how to use a safety razor or straight razor for that. I keep cutting myself. The margins seems to be quite narrow and boy does your head bleed if you cut it...so I am stuck with cartridge razors which actually works really well. Just means spending more money and dealing with clogging.
Derby or Feather blades and a cheap €15 handle. I try to shave once with the grain, once sideways. The blade is held at quite am angle but with very little pressure.
I still have many Derby blades and the safety razor from my non-beared times. Might give it another shot.
If someone knows someone in Sweden who will do a good job of making my straight razor... well, razor sharp, I'm all ears.
In the past I have used fiber optic polishing film, it works and cost around $1 a sheet. It must be stuck to a very flat surface like a glass table or your bathroom mirror. You want something in the range of 1-10 micron.
