Forging Ahead: The Art and Science of Knife Making

The video explores the evolution of knife manufacturing from the Middle Ages to modern times. It begins with the role of iron in knife making and the blacksmithing techniques used in the past. The process of forging, heating, and shaping metal is detailed, highlighting the skills of blacksmiths. Modern manufacturing techniques are then discussed, showcasing the use of robotics and increased productivity. The quenching process for hardening steel is explained, along with the introduction of stainless steel to prevent rust. The video concludes by acknowledging the legacy of blacksmiths and the continued use of forged knives today.

What is the primary component added to iron to create steel?
