For me, the journey started rather typical (for this day and age). I started out just reading and browsing the forum for a long time, trying to learn as much as I could. Then I came to the realization there's really no way to skip the book learning.
So I bought Connoisseurs and read that several times. Next I picked up Markus' Japanese Sword Smith Index. I spent a lot of time looking at dealer offerings online and cross checking it with Connoisseurs and the Index.
From the onset I had the Nanboku-cho period in mind because I love the sugata, and that particular and relatively short moment in history. I began looking at and reaeaching the top Soshu masters basically because of the reputation of being the pinnacle.
I liked Kaneuji and Norishige the most, however getting close to the master's work at my set price range was not gojng to be very realistic. Kaneuji's history was particularly investing to me, so I started looking into Naoe Shizu as a sort of way to get Nanboku-cho Soshu at Mino prices. (Rember I'm a newbie).
I liked the examples of Naoe Shizu I could find, and what really sold it was my picking up the Soshu Den Masterpieces book. The description there of Naoe Shizu being a quality blade that was sought after by actual warriors really did speak to me. Ive been through some s**t in my 15 years in law enforcement, and when I look at that work, it feels deadly but beautiful.
I don't know if that's a good reason or not
