In this video I compare the modern day 3 and 4 blade razors to the simple single blade safety razor your grandpa used.
I shave half my face with the new razors and half with the safety.
The difference is not big in my opinion and yet the price is a massive difference. You can get a year supply of razor blades for the safety razor for about 20$
A year supply of cart blades for the modern razors could easily go into the hundreds.
I also provide some tips and tricks on shaving.
