Bugyotsuji, As you have probably guessed already I am new to this. I am looking for something old, rare , high rated origami with history. I feel history of the blade is more important than the quality itself. I like The Kamakura period because I believe there are not only more blades to choose from but I also believe the Smiths were in the age of perfecting the quality of there blades.Perhaps I am looking at this the wrong way. I would like a very nice quality sword with history behind it.
