I came across the Northern Carlifornia Japanese Sword club (token kai) formed by the renown author of The Samurai Sword -- A Handbook, Jon Yumoto. I noticed in particular how detailed their Visual Glossary is. This is a great resource if you want to know more about the different aspects of the sword, its, manufacture, the different types of design of both the blade and the mountings.
I know there is a lot of detail and, I'll admit, even I don't know all of them but that just gives me more reason to read through it. Take a look and learn a little more about the swords you may use.
