A sabre and swords in terms of shape, size and use differed slightly, but the fundamentals and length of blades were quite similar in this case, giving Damian the opportunity to sharpen his technique and skill.
Against beasts, he would rely on speed, his strength and the sharpness of the blade, however, while fighting against the mercenary, he realised that there was more to wielding a blade than that.
Sabres are curved blades that have a cutting edge and are mainly used for slashing and slicing attacks.
Swords also have sharp edges, but they aren't curved and are usually thicker than sabres and also have a sharp point, making them heavy, and allowing them to be used to stab and pierce.
