Hand-forged katana: Step 6, quenching and tempering

This is the sixth video in a series. I'll be uploading a new video approximately every week as the project progresses. Each video will cover one step of the process.

In these videos I forge Japanese blades by hand. I heat treat them, polish them, and make all the parts necessary for mounting them. These videos are targeted to people who are interested in metal art, blacksmithing, forging, knife-making, and sword-making or are simply interested in maker videos. I try to present content in a calm, relaxing fashion that anyone can enjoy watching, whether you participate in this hobby or not.
My most recent blades are made from modern high carbon steel, such as W1 drill rod and custom W2 steel bars. In the future I plan on smelting my own tamahagane and making swords and daggers from that ancient steel.
