Thank you all for your great replies! It does seem like to some it is a preference, and to others it may not be necessary. I am really curious about how facial hair can actually deform steel! I am a civil engineer and I remember some material laboratories in undergrad where we would yank on a steel bar until it yielded and eventually snapped. A Ton of force! How on earth can facial hair deform a blade? Is facial hair harder than steel?

Anyways, I have 4 blades here that I am sure I will be rotating according to my heart's content! The more important issue that I am wondering about is if different grinds feel different on a strop (say a wedge vs full hollow)?

Also, when learning how to shave with different grinds, is there a big difference between say a wedge and a full hollow?

should extra attention go into the shave when changing grinds?
