The sword flew whipped through the air a lot more easily than its size would have suggested. The blade was almost as agile as a regular sword. But he soon ran into a problem. The roof of his house was too low for him to properly train with a sword. At least this new sword.
The blade was just over two meters long. If he extended his arm all the way, it would cut a hole in the ceiling. He decided to enter his courtyard for the first time. It was small in terms of courtyards but almost as big as every room in his house combined. It was large enough to train in but small enough to not let it overgrow and need servants to prune the plants.
He stood on the grass beyond the sitting area, raised the sword above his head, and gave it a strong swing, cutting with the technique of his heaven-splitting sword art. The air buzzed as the sword broke through.
