Often shaving commercials brag about how their razor has more blades than their competitors, are more blades somehow better, and if so why?

Answer: some of the ads for those blades will show you why. It’s akin to having a dual-deck riding mower–you get multiple attempts to cut each blade of grass you go over.
The first blade “cuts” (really, drags/lifts the hair out of the pore and rips it with the leading edge of that blade), then the second blade comes along immediately, before the remaining hair retracts, and again “cuts” (separates) another segment of the hair, and so on.
There’s a limit to how efficient multi-blade razors can be (six blades doesn’t get you much more than three or four), but it gives you a little “cleaner” shave (the hair remnants are now at pore level or slightly below–which has its own host of issues), which makes your face/legs/whatever smooth to the touch.
