Yes indeed, Nital is way better than ferric chloride. It is not as messy and gives a nice dark patina, depending on the quality of the wootz.

I have experimented with various concentrations of Nital, between 2-5% and 2% is a little two weak for good results. For quality, high contrast wootz 3% would be enough but would require more applications. 4% would be ideal for most wootz but you must dilute it yourself as I didn't find Nital 4% commercially available. 5% is rather strong and may leave some golden taint, but sometimes is necessary for low contrast wootz.

In order to reveal the structure, the blade must be polished to grit 2000-3000 for best results.

However, I never saw a Pata with wootz blade so I am not sure it would be worth the effort. Maybe should do a test first.

Can anybody please post some photos with Pata swords with wootz blades?!
