Hey Chris,
I wish I had a more definitive answer for your questions. Truely, I probably need to read and research more about the schools and styles of each. My plan was try and find something in that price point these was signed, maybe in old polish that I could research. Was keeping my fingers crossed for something with a nice Hamon design as it might get my wife a little more interested. Then once in it I could spend time researching as much history on the blade as I could. I would prefer something a little longer over 13” in length. I also would not mind sending one out for Polish as well. Sad to say I’m really just looking for real, signed and between the 500-1500 mark. There are a few listings on eBay but I am very hesitant to trust ebay. I went to the show in Chicago but could only stay Friday night for about an hour. Wish I could have went Saturday might have been able to snag one. I did see one with papers for 600 but just didn’t pull the trigger. I attached a photo of it. I can’t remember the seller and I misplaced his card.
