This is hard to pick sugata. The only blades I have and have seen in person are what are normal for modern day Chinese replica. Approx 28 inches Sori I forget but I think approx 1.5cm to 1.8cm and Chu kissaki.  Truthfully I think I would like a lot of them. Ok so we can take the latest six and I would take any if other features that we will get into after this are something I like. I think I like o-kissaki of course if straighter blade and chu kissaki for more curve sori in blade. This is hard because I haven’t held a katana that is straighter.   I wonder if I narrowed anything down?   And technically I think the first of the last six, middle one that is shorter and nakago is short. Probably like a wazakashi?  If a wazakashi that has longer blade would have better features and be nicer for less price I can go that way also.  Sorry it’s hard to explain this one. It’s easier for me to maybe pick other things like hamon etc.  But maybe o-kissaki with a hamon that works with it. I will know when I see a Hamon and can visualize it on the kissaki
