Now mechanical watches are popular again -- but a cheap mechanical watch manufactured today keeps far better time than a cheap one you could buy in the 1970s. This leads people who have only experienced modern mechanical watches to wonder why they ever went out of style.
Similarly, the market for safety razors today is far different than it was when cartridge razors were introduced. Back in the 1960s consumers could get their hands on just a few kinds of razors and blades, and the blades were not generally as good as the blades available today. There are simply far more, and far better, safety razors and blades available today than there ever were before.
Similar observations can be made about the fountain pen market.
The marketing for disposable systems also misleads people as to the price. Some of the people I've talked into trying safety razors were previously under the impression that safety razors were incredibly expensive, something like $200 or something nuts like that, and they had no interest in making that sort of investment. But in reality the first time you buy a safety razor and blades, you'll be spending less money than you'd spend for a new pack of cartridges. I got my razor for less than $10. It's stainless steel, I've had it for about 10 years without a spec of rust. Perfectly serviceable and cheaper than even a pack of totally disposable bic razors you find at gas stations (I used those once during a vacation; boy was that awful...)

I do it every other day, sometimes in quite a hurry and with a slant-head. I occasionally nick myself but even that is infrequent. And as others have said, it’s dirt cheap. Since starting with a safety razor a few years ago, shaving is no longer a chore.
The safety razor was the advancement over the straight razor. It's an entirely different (and at the time, new) technology from what it was replacing.
What’s kept me away from safety/straight razors are: Learning/practice. I already nick myself with a regular shaving blade.
Time: while meditative, I am in a rush sometimes and don’t want to spend twenty minutes with lather/shaving (probably an exaggeration of time).
Choices: it seems too much like a hobby, where I can’t tell what a good “starter” is.
Apologies for formatting, this is phone posting.
Nicks: I have uneven skin. I also damage myself with a cartridge razor. I get nicks with a safety razor. I get bad razor burn with a cartridge razor, depending on how much growth I have. The nicks go away after a shower. The razor burn does not. After my first safety razor shave, I've only gotten minor nicks. Pick up a styptic pencil if worried.
Time: I need two full passes to match a Harry's. Three passes exceeds a Harry's. I can do it in 10 minutes, but, if I'm in a hurry, I use a cartridge razor. Taking 15 minutes, relaxing, getting a great shave is awesome when I have the time. Sometimes I shave before bed so I can do this.
Choices: Several online companies have variety packs of blades. Get one of those, find the blade you like, order a bunch. Buy whatever razor fits your price range. Buy the most popular blade shaving cream (not soap) you think will smell OK. A cheap brush will get you going, though you don't "need" one for shaving cream. You don't need a bowl.
Hope that helps some if you decide you're interested. Watch a few videos on YouTube to get the basics. The critical rule: don't move the blade side-to-side.
Edit: Added styptic pencil note.
Now it takes me about an equal amount of time as it did using a cartridge razor, and I rarely nick myself (about as frequently as I did with a cartridge).
There are some good lists for cheap "beginner" razors online - I'd suggest trying out one of those. You can just use your normal shaving cream, too.
The bottom line for me is the crazy cost of razor cartridges. My razor blades cost 25 cents apiece, and that's on the expensive end.
Now that you mentioned it though, and especially what temp1831 said ($5 for a year's shave), it just got my attention!
Fair point, I'd mount a sharps bin high on the wall where I could reach while standing but out of reach for the young kids.
There are also a ton of amazing small batch / indie shaving soaps that pair well with safety razors.
People don't trust razors they've never heard of. Too dull. I really like my chinese Weishi brand double edge safety razor w/ standard barbasol, and have shaved for about $5 per year for the last 5 years (capex included), so I feel like an outsider looking in.
