Why is this the answer?

The answer is iron because this clever riddle tells the story of how metal is made and then used to create something sharp and dangerous. It is a fantastic puzzle that uses big, exciting words to describe a simple process of making a sword or knife. Let's look closely at the first line: "Ripped from my mother's womb." The "mother's womb" in the riddle is the earth itself. Iron does not grow on trees. It starts as a kind of rock called iron ore, which is deep inside the ground. People have to dig the rock out of the ground, or rip it from the earth, to get it. So, the iron is "born" from the earth, which is its mother. Next, the riddle says, "Beaten and burned." After the iron rock is taken from the earth, it has to be made really, really hot. This is done by putting it into a giant, very hot fire, often called a furnace or a forge. That intense heat is the "burned" part. When the iron is fiery hot, a blacksmith, who is a person who works with metal, takes a heavy hammer and pounds the iron over and over again to shape it. They "beat" it until it becomes strong and has the perfect shape for a tool. The beating and the burning both help to make the iron much tougher. Finally, we have the scary line, "I become a blood thirsty killer." While iron is used to make lots of helpful things, like nails for your house, pots for cooking dinner, or horseshoes for a horse, it can also be shaped into a fierce weapon, such as a sharp sword, spear, or knife. These sharp tools were used by warriors in battles. The riddle describes the weapon by calling it a "blood thirsty killer" because it is a tool meant to draw blood. The iron starts as a humble, cold rock, gets put through the fire and tough hammering, and ends its journey as a strong, sharp object. This riddle is a creative way to think about how natural materials are changed into something very useful through hard work and fire.
