I have been wondering about WHY there are different types of grinds to blades? I have used several types of hollow grinded blades and have noticed that they behave differently. I have not used a wedge blade yet but have been told that you will feel a big difference as well as a sound difference. When I shave with one of the hollow types I do hear a popping and snapping sound as I stroke my face. I have been told that when shaving with a wedge you should hear nothing. I assume that this is because of the blade not flexing as it cuts the hairs.
So, why have hollow ground blades???
Is it because of peoples beard hair being thinner or thicker?
Would a wedge blade be the best all around blade because of it's weight and ease of use?
I have read tons of stuff in Wiki and on peoples posts and have never seen any information on this.
