Hand-forged katana: Step 7, polishing and sharpening

This is my own take on this subject.  But it's important for me to say that I didn't invent any of these techniques.  I give credit to Walter Sorrells for anything useful I know about this subject.  Any mistakes or misapplications of the techniques are mine.

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.
