New shavers find the differences, experienced shavers note the similarities. That is just the way things develop and are a natural part of the learning process.

A new shaver will adjust their technique to the differences they observe, often necessitating doing completely new things - this is a good thing as it develops your range of experience. Eventually your technique will have developed such a range that you cease to notice the differences and begin to appreciate the similarities, or constants, that all blades share.

So the short answer is all blades shave differently until you get enough experience to realise that all blades shave the same
