So here is a flamboyant one.   Is this an authentic Yasunori mei who became a Yasukuni shrine Smith?  Thoughts on the  sword itself?     Below are pictures of the sword in question with a large temper/hamon, 28.5" nagasa in early type 98 mounts.  At the end is the mei of this sword and some other examples Yasunori mei examples I've found on some websites.  There is also a photo of the flaws that exist on the blade (few openings and nail catcher knick).
