WOOTZ or SHAM?

[ALEX]

As we know, Dr. Verhoeven does not consider sham to be true wootz, however many collectors do. And as it's relatively easy to recognize network and ladder types, it is difficult to make a clear distinction between stripy, water and wavy patterns, as all three can be labeled as sham (just look at the multitude of individual opinions from this post:

So here are two blades. Both have longish threads, more evident on Sword_One, with one particular thread looking like a half-circular brush stroke (see second picture). I even thought it was painted when I saw it first time. The second sword has similar, but less wilder threads. Both can be seen as sham, but considering relative high contrast could one see them as wavy/water type? And how do you make an informative "guess" which is which?

P.S. Glad to be joining so many dedicated and knowledgeable people at The Forum. This is my first post. Looking forward to learn and to share. Alex
