Overestimated

Jac's face turned completely ashen. The crowd on the outside hadn't even gotten to say a thing when they noticed his uncontrollable trembling. 

However, the process had already begun. 

Elder Beinala's badge, which was still on the ground beside Leonel's Force Crafting glove, suddenly began to glow. With a subtle sweep, a gentle energy rose Leonel's short sword up to meet Jac's knife. 

Jac gripped his fists, calming his breathing. 

Polished Glass was used to refine edges of blades, normally. As a result , it was known for its sharpness, but lacked in other important qualities like ductility. Due to this, it could become extremely brittle when used in large quantities. 

As an expert Crafter, Jac, of course, knew this. So he tried his best to limit the size of his Crafts. 

When he saw that Leonel had made a short sword, he almost snorted in contempt. In fact, he would have had he not instantly been shocked by Leonel's staff.
