with a Damascus blade...... there will be a VISIBLE grain of sorts.....
no matter what you do youll end up with the middle pic. other wise itll just look like one plain piece of steel, except on the spine. youll have to grind THROUGH the layers to expose the pattern/grain.
now comes what ray said...... during heat treat, the individual grains of each layer will realign if the billet was forge welded properly.
wootz steel..... someone else will have to chime in on that one. that stuff is still within the realm of "magic" for me.
