Totally agree with Papabull.

Scales have a very sophisticated design developed over many years. Some razors are balanced much more finely than others. Lead or pewter was used as the balancing weight because they are soft metals which could be easily shaved of weight to achieve the correct balance.

Most importantly, scales balance the razor in the hand whilst shaving. Just a gentle touch with the thumb will swing the blade effortlessly towards or away from the skin. When you hold a razor, you can tell instantly if it is well balanced or not. I do not know how the manufacturers weighted the scales other than by hand but I do know its not by chance that some razors are superbly balanced.

High quality razors are just a delight to hold and use. You don't have to grip them, they balance in the hand and the natural shaving position perfectly. Whatever the blade size, a good razor is always complemented by a balancing set of hand weighted scales.

Does it matter. Well its like the difference between a fine writing instrument or a bic biro They both work but the one is much more pleasant experience to use than the other.

I remember my Mother would always check new cutlery by checking the balance on a fork. She would say, they all know how to balance the knife, always check the fork or a spoon and that always sorts the men from the boys.

It's the same with a good razor. It should balance in the hand whilst shaving without you having to even think about it.

IMHO if your razor doesn't do this, you are missing a trick.
