Last time I was gonna by blades at the local store was about 10 years ago. I was sufficiently miffed at the corporatocracy's price skimming and gouging that I hopped on the intertubes and bought about $20 worth of twin- or triple-blade cartridges from India. And there will likely be inventory on hand when I die.
Ooh, yes but no. Those 42-blade razors are garbage, but the Holy Grail of close shaves (imo) is the safety razor. Feels much more comfortable to use, and, well, is safer.
I will say that I do get more razor nicks using a safety razor but it's pretty effective at getting that good close shave + I save money and it's better for the environment
It's just that safety razors are often considered to be a thing of shaving enthusiasts, and if you go through that rabbit hole, you commonly go all the way.
They're definitely cheaper than using cartridge razors, but personally I found decent cartridge razors just get a closer shave than safety razors. And it wasn't for failing to learn how to use a safety razor either. I used one for several years, got good at it, but later switched back to cartridge razors on a whim and found that they simply get reliably closer shave than a single blade does. I still use soap and a brush rather than canned shaving cream, because it is much better and more economical, but for me the closer shave that comes with a cartridge razor is worth the price.
It seems to depend on your face and skin. For me, single-bladed safety razors deliver a closer shave with less irritation compared to cartridge, and I experimented quite much with both.
Still, the cult of safety razors is sometimes overblown. Just pick what fits you best.
hashtag not sponsored, my current razor is a Leaf. great little thing, it takes three single-sided blades (or 1.5 normal ones snapped it half) and is used just like a cartridge razor. it's a bit expensive at €80 or so, but it's completely metal so i expect it to outlast most other stuff in my bathroom.
