OK, now I know. It just required an appropriate leather glove and the "feeling" and grip of the sword completely changed. Bare hand is insufficient for this hilt. It feels somehow thin or too big and the thumb ring doesn`t feel good at all. With glove the sword becomes part of your hand. The grip gets ubelievably strong and comfortable. The sword becomes very fast and precise.

And it certainly can swish and slash. Such an inconspicuous blade. I fell in love.
