I've found 4 is pretty good for me. Going to try 5 soon though. I also flip the blade after a week to get the other edge when it starts hanging up

Flip the blade eh? I got a pack of 100 for like 20 bucks, so am switching them pretty liberally thus far. Reusing old blades was the bane of my existence with the prior expensive 5-blade scams
Flip it. Trust me bro lol. Seriously though it takes 10 seconds and there's the other edge of the razor blade that's not being used. Just grab from non edged sides lol.
It shaves both directions, right? Will try flipping it. And yeah, I'm very careful when I handle them. The blades frighten me a little
