"It's a standard Duel Disk model for Action Duels. You can get one of those in almost every Card Shop. Also you can try to get one from school. But if you don't like to study, it's a bad idea. But it's possible that you already have one of those and just never discovered this function. It may took a while to discover all of it's functionalities." Vern answered question, explaining everything he knew on this topic. "Well to be honest I modified my model a little, but none of the original features were removed from it. It's just a blade modification and nobody will care about it. I'm not even sure if it's counted as a proper modification. And that's all on this topic." He finalized his monologue. There wasn't a single reason to not talk about blade modification. That wasn't so common thing, because it requires a lot of work on blade program, which requires you to know more than basic knowledge on how solid vision works, but it's a thing that some people do. Vern probably would never manage to do it on his own for the first time, but thanks to his father, he learned how to change it properly by himself.
