Karl started HEMA in 2008, training in italian rapier and sabre as well as sword & Buckler (I.33). Since 2013 he's focusing mainly on rapier and became the main italian rapier instructor at Klingenspiel, Vienna. He's literally obsessed about Ridolfo Capoferro's treatise (mainly because he still doesn't understand everything in it, which drives him nuts every so often). He also likes to play with rapier against different weapons, be it longsword, sabre, sword and buckler or spear. Inofficially his rapier is called ""the beast"" by some serbian HEMA colleagues because it's longer and heavier than any other rapier they encountered so far.
