It's insane what goes into making the tamahagane. It takes about 10 tons of satetsu and 12 tons of charcol just to get a 2 ton kera. Can't imagine what they do with all the slag metal. Made a wakizashi using orishagane with differential tempering. Its difficult to make a clay that will stick to the blade during the tempering process. Took me three attempts and three blades.
wow sounds like an amazing experience id love to go to japan some furhter study in jitz and maybe some judo and bjj at tiger palace and do stuff like this !!!
If your in the US you should try just some furnace cement that you get at ACE or look on the net for satanite. I use satanite for the most part, but either will work.
There are two course: This one takes a week, or there is a day course where you make it from a preformed shape and refine the surface, apply the clay and quench it yourself.
