I have been watching a few forged in fire episodes(for those of you that don't know, it's this show kind of like a masterchef for blacksmiths, where a group of blacksmiths all have to compete and make certain types of blades every episode) and there is something that I don't understand. These professional blacksmiths usually take 3 hours to work on the blade of a dagger alone, usually taking a few more hours to make a handle, and they can take days to craft a bigger sword. And even after all that crafting time, most blades bend or break after a bit of use. So my question is, how did medieval blacksmiths make enough durable and effective weapons and armor to fuel all the wars that happened in Europe at the time?
