I found the bit about which type of razor to pick for which type of beard interesting.

I also found this interesting. I’ve only used hollow grind razors, and would love to try other grinds at some point.

I have to say I’m skeptical about the grind needing to be different for different types of facial hair though. I’d assume that as long as a razor is sharp it’ll shave well with good technique. I’ve definitely been wrong before though!
