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.

I thought that the purpose of making hearth steel was to add carbon into a low carbon steel. What's the point of making hearth steel from an alloy which is already high in carbon? Thanks.

You are correct that that is one purpose. It's not the only one, though. 1) In ancient times it was also a method of consolidating scraps into a useful piece, essentially recycling. Ancient people couldn't afford to throw away steel scraps of any grade. 2) Depending on the characteristics of the fire, it could be used to remove carbon. Lots of what comes out of a tatara is cast iron or pig iron and needs carbon removed. One interesting modern application of this principle occurred during WWII when swordsmiths who couldn't get tamahagane made hearth steel (oroshigane) from broken bits of cast iron from pots purchased at flea markets. My purpose in this exercise was just to produce a puck that would physically resemble ancient steel, that I could practice working using ancient techniques. I didn't care about carbon content

@@oldpuebloforgeAh great, that makes sense. Thank you.
