Mach 3 was about the epitomy of the mutli blade razer, twins suck, and those with more than 3 have their blades so close together they are useless if you have more than a days worth of stubble, because they get clogged up.
With a Mach 3 can shave a weeks worth of stubble to clean in a few minutes.
Of course closest you will ever get is with a true straight edge used by a pro, but most of us can’t afford to pay a barber to give us a shave daily.
using a waterpic can clean out the razor clogs. A hand towel next to your razor can dry it off leading to MONTHS of use.
