Gee, you guys get all rilled up over these things.
I'm just going to say what I've said many times here. If you prefer a particular grind or size because you just prefer it and enjoy it thats one thing but if you do it because you think its the only type you can get a decent shave with that's another thing.
If you could time travel to a barber shop in the 1930s,40,50s you would find full hollow grinds and mostly 5/8s and 6/8s being used. Barbers had to shave everyone who came into the shop with those types and they did it very well. If you needed a certain blade for a certain type of beard then this should not have been possible. It was mostly old timers who learned in the early parts of the 20 century who liked their wedges and they used them on everybody.
Those are just the facts guys.
