That's what Japanese are known for. taking something and making it their craft with a lifetime of dedication and passing it down to their heirs. And the result of that is japanese knife makers improving their craft over time in the pursuit of perfection. That to me is a level of of craftsmanship that will take different cultures a lifetime to catch up too. Think Japanese culture tends to pass down professions from generation to generation. Or we'll at least the some still do. Although Japanese culture is becoming more westernized some traditionalist still exist and you can see that in knife and sword making.
