Making the coil spring

"Woman, what do you think is the use of this thing? We have been building unusual items since his majesty arrived at this guild and I am utterly confused as to what all these items with strange forms would be used for. Before, we used to fabricate simple items like steel bars and farm tools and equipments, but nowadays, we have been ordered to fabricate strange items in that it is even making me feel like his majesty is playing with our occupation. Just look at this fucking huge spring that we are making, what will it be used for?" A disheveled blacksmith with an unclothed torso stopped hammering the coil spring into shape and wiped out the sweat on his face. He was chatting with his fellow blacksmith who was doing a different chore as compared to his and he could not help but ask her this question.
