The Weapons I Forge are Absolutely Flawless

"Why do you think the first sword used by the hero was called the Village Sword?" "As the name suggests, it was the best iron sword in the village." "What if the village had a better iron sword?" "Then add +1 after the name." "But the number is +9527. Are you really not just trying to ride on the hero's popularity?" "Innovation and striving for excellence are my duties as a craftsman." ... "Weiner, we have received a report that you are mass-producing counterfeit and shoddy products. A large number of users have experienced damage to their equipment during battle." "That's nonsense! There is absolutely no problem with the weapons I forged!" "Then how do you explain this fact?" "That's easy. They used my spear to pierce my shield, and the shield went through. Is it because my spear is of good quality or my shield is of poor quality?"
