Adam. I am Jason and I am also a begniner being about 3 years now. For you, it's absolutely the time to invest books. I beleive you have been building for your own interest and knowledges thru internet but that is very limted and the idea would be clustered. With books and swords on your hands, you are now finally be ready to be a Japanese sword student. As of now, I see myself it's going to be a really the long way to go to be good level of understanding the whole of it. However, without books, it is basically impossible to go further. I am sure you can get good books list around here and there are links on this forum.
