WOOTZ or SHAM?

On the patttern welded blades, the left has a low number of layers, the right a high number. Unevenness in the surface from hammering (that is later filed out) results in more layers being exposed on the surface, which is what Figiel must have been referring to when he spoke of peining.
Another factor which influences the way patterns show up on these blades is the state of hardness of the metal - A blade or area that has been fully transformed in the hardening process will etch more slowly than an area that was not hot enough or cooled too slowly to harden properly.
