My copy arrived today. I think this will become a standard reference work in English language regarding tosogu. It's projects like this that make it easier for people to get into this hobby, tearing down the language barrier. Really an amazing job! The pictures could've been better, but that's understandable, seeing Markus didn't have access to the originals and seeing it's a Lulu publication. Otherwise the cost would've been a lot higher.
This one gives you a lot of bang for your buck! (to use a colloquialisme). Sorry for the poor mobile pictures, but I hope they give you an idea about the wealth of info in this publication!
So everyone out there reaping the benefits of these publications, join a Japanese Sword Society and pitch in! A big thank you to Markus but also the various donators needed for this project and Mr Grey Doffin for proof reading!
