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.
That and the fact that I bought $20 in razors like 2 years ago and I’ve yet to buy more.
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.
I prefer electrolysis.
