Actually the wootz phenomenon was much admired by Europeans, and through the 18th century there was a degree of study and attempt to reverse engineer this high carbon steel. I know so little on metallurgy that I can only recount historical record in noting that reasonable 'interpretations' of wootz were produced by 1790s early 1800s in England, but most impressive were the Russian versions known as 'bulat'. Unfortunately the scientist passed away before he published his work.

While more cannot be said briefly, despite some cases of wootz-like steel, it was not something widely nor certainly commercially known or used in Europe. Even in India and the Middle East, the art was lost, and trade blades became the norm.

The source of schiavona blades is a well placed question, and it appears that the early examples were of course from Italian centers, notably of course Belluno, and makers in those regions from Milan, Lucca and others.
Mostly there are 'guild' associated marks but not always identifiable to a certain maker. It seems the case where a makers name is on the blade would be most unusual.

By the 17th century, the south German makers as well as locations in Styria supplied blades used for mounting these type hilts in Italy. There are cases where Croatian or Slavic names have been found, but I believe on hilts.
As the term for 'schiavona' for these swords suggests, these were traditionally associated with Slavic troops guarding the Doges Palace in Venice thus the term that ended up being used. These were typically Dalmatian (Croatian).
These swords were used not only throughout other Italian locations but somewhat in other contexts where Italy had presence.

The 'kings head' on one schiavona blade (Wundes, 1580-1610 Solingen; unidentified mark on another, likely Italian and another 'marca di Mosca' noted from the centers situated in and around Belluno (of course the location of the fabled Andrea Ferara).
