In the mid 17th century the butt-plate started extending all the way to the quillions (photo 17) making the metallic assembly of the hilt look like a one piece solid completely enclosed protection , a style so different from the incipient scimitar montures.
Worth mentioning is that up to 17th century (some parts even later) many cavalry trooper carried a secondary weapon, an oversized straight long sword named kontchar (a term that not 100% safe to use but scholars tend to nowadays) used to pierce chainmail and breech trough enemy lines, which proved less convenient than the classic lance; the lance was a weapon almost forgotten by the cavalry of western Europe in the 17th and 18th century until the amazing grace and force of Polish uhlans (lancers) amazed Napoleon and immediately reintroduced them lasting one more good one hundred years.
Another improvement of the hilt is the use of ray, shark (photo 20) or other similar skins that provide superior grip in battle or the use of wire wrap over leather providing similar qualities, the last being encountered before in Europe and therefore not completely new.
That is the beginning of the ,,epee a la Hussarde,, or Hussar style saber (photo 19) who was adopted quickly by all most powerful armies of Europe from Hungarian by Austrians then Prussian, French and British and ended up glorified by the Napoleonian Era wars (photo 20) and in the 18th century it ceased to be ,, Hungaro-Polish,, and it became the European curved saber hence its mainstream adoption as it started expanding west via the armies of the Austro-Hungarian Empire and its conflicts in the 17th century and culminating with the ever popular sabers of ,,Blucher,, type (see photo 21) which are nothing but ,,epee a la Hussarde,, , a Hussar saber.
