Interesting topic… (and one I’d never guessed that I’d see here… lol)
But to answer the question, Gillette Mach 3.
I latched onto it what? maybe 20 years ago now, and I didn’t bother to look further.
I LOVE the combination of the “grippiness” that the rubber provides while wet, but still has the weight and durability (while in the travel bag) to feel substantial. I’ve never had to replace the main body, and while I don’t particularly care for the price of the replacement blades (ok, cartridges)… I don’t get sliced and diced by it like I did with a host of others I used before it.
I’ve also used a couple different Norelco electrics (a couple decades ago) but, to me, they just didn’t cut as close. Loved the feel of the devices. Didn’t like the limited options on the pre-shave liquid though. Still have one like brand new in the overhead bin in bathroom. But it’s been gathering dust for at least ten years now, and the batteries are probably in need of replacement from neglect.
