One man's meat is another man's poison. For years I went back and forth between a Mach3 and a host of DEs and SEs, but I am now an inveterate Mach3 user. I find the Mach3 gives me a better overall shave than any modern or vintage DEs and SEs I've used. Moreover, I can usually get 10 shaves, 2/3 passes each, and often more, with one cartridge. I've been shaving for 50 years and that's my personal experience!I have no clue what im trying to read here. a lot of screaming and kicking. and a lot of misinformation from my own personal experience.
A cartridge razor is not any safer or more dangerous then a real razor, DE or SE. its just less intimidating. A lot of people I know are to damn scared to try a real razor because they think the blades will rip them all to hell.
Just try sliding a cartridge of your choice sideways on your face, wow, you get cut. just like a real razor.
Last and last? I can barely get a cartridge razor of schick quatro or mach 3 or fusion to last more then 3 miserable lousy ass shaves. IF I can get them to last more then 1 shave.
The ONLY carts that were worth a damn are the old early 1990s puppies with 2 blades and the old style tissue paper style lube strip on top
