Karlstraße was raised in a hockey family, so his introduction to the game was very early on and without much choice in the matter. His father, Nikolaus Scholz, is a Blizzard alumni and SHL Hall of Fame member, so when the time came to enroll young Karlstraße in a sport, hockey was naturally the first attempt. The game didn't come that naturally to him, however with diligence and a lot of practice he became quite comfortable on skates and soon after developed a decent set of hands. Originally thought to play forward like his old man, Karlstraße display an uncanny ability and desire to roam his own end of the ice. While he would enjoy the odd breakout, he got much more satisfaction shutting down the opposing team on the back check. When it came time to choose a position and stick to it, he opted to try his luck as a defenseman and he hasn't regretted the decision since.
