Hidden wootz

[archer]

Lou, I thought I read that finer crystalline wootz was used for added strength.
Hers the knife from a previous post. I thought that the joint was present , the etchant definitely confirmed it. Obtaining acids is a problem this is well diluted, maybe too much so. The fact that a low grade etches results are hard to see.
More shots in my post Zirah Bouk/Pesh Kabz, sorry I don't know how to link it.

I added another shot from top of weld.
